How to count down to an exact date and time

Enter a booked moment in the event's zone

Have the confirmed local date, time and location ready. Use timed mode for a flight, performance or other exact start.

1. Open the countdown and tap the pencil.
2. Expand Optional timing and place and enable Include a target time.
3. Enter the source's calendar date and clock time.
4. Choose the Time zone that belongs to that source time.
5. Review Countdown detail if you want a more precise display.
6. Tap Save and compare the saved target with the current booking.

Calendar days and exact times

A timed countdown counts toward a specific moment. A date-only countdown counts calendar days, so the numbers can differ near midnight. The hours and minutes calculators here use UTC.

Check the time and time zone

Check both the time and zone if the duration is unexpectedly long or short. For travel, keep a separate airport-arrival plan. A countdown to departure is not an instruction to leave home at that moment, and it does not monitor delays.

If the exact count differs from calendar days

The timed mark measures the wait until a moment. The date-only tool counts date transitions. They need not match near midnight or a daylight-saving change. Do not move a correct booking merely to match a whole-day number.
