About this countdown
How does the 1 AM countdown work?
The timer counts down to the next 1:00 AM on your device's clock, in your local time zone. If 1:00 AM has already passed today, it counts to tomorrow. It stays correct across midnight and daylight saving time changes, and a reload shows the same result.
What happens when the timer reaches zero?
The timer shows 00:00:00 for a minute, then moves on to the next 1:00 AM. With Sound on, it plays a short alarm. Keep this tab open: a closed page can't sound an alarm.
What is 1 AM in 24-hour time?
1:00 AM is 01:00 in 24-hour time.
