Current time: live local time, date, day of week, and timezone

The current time tool displays your local time updated to the exact second, alongside the full date, day of the week, and your device's time zone. Toggle between 12-hour AM/PM and 24-hour formats at any time. The display is driven by your device's system clock, so it is always accurate without needing an internet connection after the page loads.

How the live time display works

The page reads the current date and time from your browser's built-in Date object, which reflects your operating system's clock. A JavaScript interval function fires every 500 milliseconds — twice per second — to refresh the display. The half-second refresh rate ensures the seconds digit never appears to skip a beat even if the interval fires slightly late due to browser load.

The time zone identifier (for example, "America/New_York" or "Europe/London") is read directly from the browser using the Intl.DateTimeFormat API. The UTC offset (for example, GMT−5:00) is calculated from the difference between local time and UTC. Daylight saving transitions are handled automatically by the operating system — no manual adjustment is needed.

UTC offset (hours) = Local time − UTC time

A positive offset means east of UTC; negative means west.

Uses for a live current-time display

Presenters and online hosts use the current-time page as a full-screen clock during virtual meetings, visible behind other windows or on a secondary monitor. Teachers use it as a classroom clock when a physical clock is not available. Remote workers use it to cross-check their local time against scheduled meeting times in other zones.

The 24-hour format (military time) is useful for international communication because it eliminates the AM/PM ambiguity. For example, 14:30 is unambiguous, whereas "2:30" requires context. Many industries — aviation, medicine, emergency services, and the military — use 24-hour time exclusively.

Frequently asked questions

Is the time shown accurate?

The time comes from your device's system clock, which is typically synchronised with internet time servers (NTP) and accurate to within a fraction of a second. If your computer's clock is wrong, the display will reflect that. Check your operating system's date and time settings if you suspect an inaccuracy.

 What is the difference between 12-hour and 24-hour time?

12-hour time repeats the hours 1–12 twice per day, using AM (before noon) and PM (after noon) to distinguish them. 24-hour time uses the hours 0–23 with no AM/PM suffix, eliminating ambiguity. Midnight is 12:00 AM in 12-hour format and 00:00 in 24-hour format.

 What does UTC offset mean?

UTC (Coordinated Universal Time) is the global time standard. Your UTC offset is how many hours and minutes your local time zone is ahead of (positive) or behind (negative) UTC. For example, Eastern Standard Time is UTC−5, meaning it is 5 hours behind UTC. During daylight saving, the offset shifts by one hour.
