How many hours are left until tomorrow?
The counter above shows exactly how long is left until midnight — the moment today ends and tomorrow begins. It reads your device's clock and time zone, so the number is correct wherever you are, and it updates every second. "Tomorrow" starts at 12:00 AM (00:00), so the hours until tomorrow are simply the hours between now and the next midnight.
Is midnight 12 AM or 12 PM?
Midnight is 12:00 AM — the start of a new day. In 24-hour time it's written 00:00. Noon, in the middle of the day, is 12:00 PM (12:00). So when this page counts down to "midnight", it's counting to 00:00 at the very start of tomorrow.
How much of today is left?
A full day is 24 hours (86,400 seconds). The progress bar above shows how much of today has already passed and how much remains. At 6:00 PM, for example, three-quarters of the day is gone and there are 6 hours left until tomorrow.
