Use it as a Buddhist holiday calendar worksheet This page is designed to answer more than “when is Vesak?” It helps you estimate Buddhist holiday dates by year, compare Theravada, Mahayana, and Tibetan anchors, and see which observances deserve local confirmation before you lock in plans.How the dates are estimated Theravada observances are tied to lunar full-moon timing, Mahayana calendars keep some fixed civil dates, and Tibetan observances follow a separate lunisolar cycle. The result is strongest as a planning sheet, not as a substitute for a local temple calendar.
Why the page is structured this way
Competitor pages usually either list a few holidays without context or explain Buddhist calendars without helping you plan the year. This worksheet is meant to do both in one place.
The most important caveat is tradition drift: Theravada, Mahayana, and Tibetan communities can use different calendar rules, and local temples may publish a final observance date that differs from the broad planning date shown here.

Losar
Tibetan
Feb 17, 2026
Tibetan New Year, celebrated on the first day of the first Tibetan lunar month. Festivities typically last for fifteen days.
Timing basis: First day of the Tibetan lunar year
Typical window: Late January to March
Planning note: Treat this as a strong Tibetan/Vajrayana planning anchor when you need the start of the festival cycle.
Makha Bucha
Theravada
Mar 3, 2026
Commemorates a gathering of 1,250 enlightened monks who came to pay respect to the Buddha without prior arrangement. Observed on the full moon of the 3rd lunar month.

Typical window: February to March
Planning note: Good first-quarter Theravada anchor for community calendars and education planning.
Vesak
All
May 31, 2026
The most sacred Buddhist holiday, celebrating the birth, enlightenment, and death of the Buddha. Observed on the full moon of the 4th or 6th lunar month.
Timing basis: Full-moon observance with different tradition-specific calendar rules
Typical window: April to June
Planning note: This is the main cross-tradition search intent and the most important date to sanity-check early.
Asalha Puja
Theravada
Jul 29, 2026
Marks the day the Buddha delivered his first sermon at the Deer Park in Sarnath. Observed on the full moon of the 8th lunar month.

Parinirvana Day
Mahayana
Feb 15, 2026
Fixed Gregorian observance in many Mahayana calendars
Mid-February
Useful as a stable Mahayana reference point for annual teaching calendars and temple notices.
Some Tibetan and East Asian communities keep different parinirvana commemorations, so local temple schedules still take priority.
Losar
Tibetan
Feb 17, 2026
First day of the Tibetan lunar year
Late January to March
Treat this as a strong Tibetan/Vajrayana planning anchor when you need the start of the festival cycle.
Losar dates are often calculated locally and can vary by region, monastery, or community lineage.
Makha Bucha
Theravada
Mar 3, 2026
Theravada full-moon observance of the 3rd lunar month
February to March
Good first-quarter Theravada anchor for community calendars and education planning.
Country calendars may publish a different civil date based on local lunar calculations or public-holiday handling.
Vesak
All
May 31, 2026
Full-moon observance with different tradition-specific calendar rules
April to June
This is the main cross-tradition search intent and the most important date to sanity-check early.
Theravada, Mahayana, and Tibetan communities can observe Vesak or Buddha Day on different civil dates in the same year.
Asalha Puja
Theravada
Jul 29, 2026
Theravada full-moon observance of the 8th lunar month
July to August
Useful for marking the Dharma Day season and the start of Vassa-related planning.
Some calendars publish adjacent civil dates or weekend observances, so temple confirmation remains important.
Vassa
Theravada
Jul 30, 2026
Begins the day after Asalha Puja in Theravada calendars
Usually July to August start date
Helpful when users need the retreat start rather than only the feast day that precedes it.
Retreat practice is not universal across all Buddhist traditions, and local monasteries may communicate the season differently.
Pavarana
Theravada
Oct 25, 2026
Theravada full-moon observance marking the close of Vassa
September to October
Useful if you need the end of the rains retreat rather than only its beginning.
Pavarana is commonly handled within local Theravada calendars, so the published community date may vary.
Kathina
Theravada
Oct 26, 2026
Offering season immediately after Pavarana
October to November
Best treated as the start of the Kathina offering period rather than one universal ceremony date.
Individual temples schedule their Kathina ceremony within an allowed seasonal window, so a local date can differ significantly.
Bodhi Day
Mahayana
Dec 8, 2026
Fixed Gregorian observance in many East Asian Mahayana communities
Early December
A dependable year-end anchor for school, temple, and editorial calendars.
Some communities observe enlightenment on other lunar dates or fold it into a broader Vesak cycle.
Tradition and local-calendar note A Buddhist holiday calculator should not pretend one civil date settles every tradition. Use the worksheet to narrow the likely window, then confirm the final published observance with the community calendar you actually follow.
Where the result is most actionable
Good uses for this page
Annual school calendars, editorial planning, travel timing, temple communications drafts, and cross-tradition comparison work all benefit from seeing the main Buddhist holiday dates in one sheet.
When to confirm locally
Confirm locally when a ceremony, public notice, retreat booking, or community event depends on the exact civil date used by one temple, monastery, or country-specific calendar authority.
Supporting observances in the yearly sequence
Beyond the headline anchors, this page keeps the supporting Theravada rhythm visible. Vassa, Pavarana, and Kathina matter because many users are planning around a season of observance, not a single isolated day.
Fixed Mahayana observances such as Parinirvana Day and Bodhi Day also stay on the sheet because they answer a different search intent: users often need one page that covers both moving Buddhist festival dates and stable calendar reminders.
Regional observances to confirm
Strong Buddhist festival calendars also surface regional observances such as Mahayana New Year, Hanamatsuri, Songkran, Saga Dawa, and Ullambana. This checklist keeps them visible without pretending one civil date fits every community.
Mahayana New Year
Mahayana
Jan 3, 2026 in many first-full-moon references
Useful when users need an East Asian Mahayana new-year planning anchor rather than a Theravada or Tibetan New Year.
Local check: Confirm with the specific Chinese, Korean, Vietnamese, Japanese, or diaspora community calendar because Lunar New Year and temple observance rules can differ.
Hanamatsuri / Buddha Birthday
Mahayana
Apr 8, 2026 in Japan; lunar fourth-month observances elsewhere
Captures the common search intent for Buddha Birthday separate from Vesak in East Asian Mahayana practice.
Local check: Do not treat April 8 as universal; China, Korea, Vietnam, Taiwan, and diaspora communities may use a lunar-calendar date.
Songkran / Thingyan / Southeast Asian New Year
Regional
Apr 13-15, 2026 in many Southeast Asian civil calendars
Helps users catch the large public-facing Buddhist cultural season that date-list competitors often surface separately from Vesak.
Local check: Country public-holiday handling and local temple schedules can extend or shift the practical observance window.
Saga Dawa
Tibetan
Tibetan fourth lunar month, usually May or June
Important for Vajrayana users because it covers a Tibetan Buddha-month intent that a Theravada-only worksheet would miss.
Local check: Use a Tibetan Buddhist calendar or monastery notice for the exact local civil date.
Ullambana / Obon / Hungry Ghost Festival
Mahayana
Seventh lunar month or mid-August in some civil calendars
Adds ancestor and merit-offering observances that appear in broader Buddhist festival calendars.
Local check: Names, dates, and ritual emphasis differ across China, Japan, Taiwan, Singapore, Vietnam, and diaspora communities.
Buddhist holiday calculator for Vesak, Losar, Bodhi Day, and Buddhist festival dates
Use this Buddhist holiday calculator to estimate major Buddhist holiday dates by year, including Vesak, Makha Bucha, Asalha Puja, Vassa, Pavarana, Kathina, Bodhi Day, and Losar. The page is built as a Buddhist holiday calendar worksheet rather than a bare list, so it shows which observances are strong planning anchors, which ones vary most by tradition, and why a local temple calendar can still differ from a generic cross-tradition estimate.
What this Buddhist holiday calculator is designed to answer
Searchers looking for a Buddhist holiday calendar are usually trying to solve a practical problem, not just read background theory. They want to know when the main observances are likely to fall in a given Gregorian year, how Theravada, Mahayana, and Tibetan dates differ, and which dates are safe to use for broad planning before a local community publishes the final calendar.
That is why this page leads with the strongest yearly anchors first, then expands into the supporting observances that shape the Buddhist calendar rhythm. In other words, it functions as both a Buddhist holiday calculator and a Buddhist festival dates worksheet, with enough context to help you make better scheduling decisions instead of staring at a flat list of dates.
How the calculator estimates Buddhist festival dates
Theravada observances are often tied to lunar months and full-moon Uposatha timing, so the calculator uses curated recent-year dates where available and a simplified lunar-cycle fallback for other supported years. Mahayana observances such as Bodhi Day and Parinirvana Day are frequently kept on fixed Gregorian dates, while Tibetan observances such as Losar follow a separate lunisolar rhythm.
That means the page is strongest as a planning tool rather than as a final local authority. It can tell you the likely civil-calendar position of Vesak, Makha Bucha, or Asalha Puja in a selected year, but it should not be treated as the last word when one specific temple, monastery, or national Buddhist organisation has already issued its own observance calendar.
timeanddate.com - The Buddhist Calendar — Explains the lunisolar structure of the Buddhist calendar and why Magha Puja and Asalha Puja move on the Gregorian calendar.
Why Buddhist holiday dates differ by tradition and country
The same festival name can map to different calendar systems. Theravada communities in Thailand, Sri Lanka, Laos, Cambodia, and Myanmar often publish lunar-date observances linked to local full-moon calculations. Mahayana communities in East Asia may keep some observances on fixed Gregorian dates or use local lunar conventions. Tibetan and Vajrayana communities add a different New Year and festival cycle again.
Vesak is the clearest example of this split. It is widely recognised as commemorating the Buddha’s birth, enlightenment, and passing away, but the actual civil date used by a community can differ sharply across traditions and countries. Losar is another example: even within Tibetan practice, regional calculation methods can shift the published date.

Regional Buddhist observances the calculator keeps visible
A strong Buddhist festival calendar should not stop at the same few headline dates. Competitor calendars often surface Mahayana New Year, Hanamatsuri or Buddha Birthday, Songkran and Thingyan, Saga Dawa, Ullambana, Obon, Uposatha, and Buddhist Era year context because those terms match real planning questions from different Buddhist communities.
The calculator now separates those regional observances from the main calculated worksheet. That is intentional: it gives you a broader checklist for Buddhist holiday planning while avoiding the false precision of assigning one global civil date to traditions that rely on local lunar calendars, national public-holiday rules, or monastery-specific announcements.
Worked example: using the page as a Buddhist holiday calendar for 2026
Suppose you enter 2026. The result sheet gives you Losar in February, Makha Bucha in early March, Vesak at the end of May, Asalha Puja in late July, and the retreat-linked Theravada sequence from Vassa to Pavarana and Kathina later in the year. That is already more useful than a single holiday card because it helps you see the year as a religious calendar pattern rather than as unrelated isolated dates.
The planning notes matter just as much as the dates themselves. A fixed Mahayana observance such as Bodhi Day is relatively easy to use in a school, editorial, or temple reminder calendar. A moving date such as Vesak or Losar is more likely to require local confirmation. The calculator is strongest when it helps you distinguish those two planning cases quickly.
What this Buddhist holiday calendar cannot guarantee
This calculator does not attempt to replace the final calendar issued by a local monastery, temple, or national Buddhist body. Communities may apply different lunar calculations, public-holiday handling, translation choices, or weekend observance practices. Some supporting observances, such as Kathina, may also be treated as a seasonal window rather than one globally universal ceremony date.
Use the result as an approximate cross-tradition reference. If the date will control travel, publication, ceremony timing, school closure planning, or an event that depends on one community’s actual observance, confirm the final civil date with that community before treating the result as locked.
Vesak, also called Buddha Day or Buddha Purnima, commemorates the Buddha’s birth, enlightenment, and passing away. It is the most important Buddhist holiday for many communities, but the civil date can vary by tradition and country.
Why do Buddhist holidays fall on different dates in different places?
Different Buddhist traditions use different calendar conventions. Theravada observances often follow local lunisolar full-moon timing, many Mahayana communities keep some dates on fixed Gregorian days, and Tibetan Buddhism follows its own lunar calendar cycle.
Is this page a Buddhist holiday calculator or a Buddhist holiday calendar?
It works as both. You choose a year as you would in a calculator, and the result is presented as a practical Buddhist holiday calendar sheet with timing basis, planning notes, and local-check guidance.
What is Vassa?
Vassa is the three-month rains retreat observed in Theravada Buddhism. It begins the day after Asalha Puja and ends at Pavarana, which is why the calculator keeps those dates together instead of showing only one festival in isolation.
Why is Losar treated differently from Vesak or Bodhi Day?
Losar belongs to the Tibetan lunar calendar and can vary more by region and lineage, while Bodhi Day is often kept on a fixed December date in East Asian Mahayana calendars. Vesak is widely shared across traditions but still does not always land on the same civil date everywhere.
Why does the calculator show regional observances such as Songkran, Saga Dawa, and Ullambana separately?
Those observances are important in many Buddhist festival calendars, but they are not governed by one universal civil-date rule. Showing them as a regional confirmation checklist helps users remember the planning intent without overstating the calculator’s precision.
What is the Buddhist Era year in the result?
The Buddhist Era year is a calendar-year reference used in several Theravada countries. A common planning conversion adds 543 to the Gregorian year, so the calculator displays it as context rather than as a separate holiday date.
Should I trust the calculator or my local temple calendar?
Use the calculator for planning, comparison, and education, then treat your local temple, monastery, or Buddhist organisation as the final authority when an exact observance date matters.
