How long until 3 AM?

Why a clock time countdown is different

Unlike a date, 3 AM happens every day. The page therefore counts in hours, minutes and seconds.

Crossing midnight or noon is where mental sums go wrong, and 3 AM is often close to one of them. The page counts in seconds from your clock, so the answer is right at any hour.

Each visit finds the nearest 3 AM ahead of you. If today's has gone, tomorrow's is used.

For short waits to 3 AM, the minutes tile is the one to watch. For long ones, read the hours. The page keeps all three units in step from a single reading of your clock.

A short bar means 3 AM has just passed. A long bar means the next one is close.

A full cycle from one 3 AM to the next lasts one day. The page shows where you are in that cycle. The bar at the top fills as the day moves along.

Working across time zones

The world has many versions of 3 AM. This page shows yours and compares it with a handful of others.

Treat the table as a check on fairness. It shows who is waking up and who is going to bed at 3 AM.

A few weeks each spring and autumn the gaps are odd. Countries change their clocks on different dates.

If your device clock is set to the wrong zone, the count will be off. Fix the setting, or choose the right city in the picker, and the page recalculates at once.

Using the countdown

The distance to 3 AM shrinks every second, and the page keeps pace without a reload. Leave it open on a second screen and glance at it now and then.

Whether it is a call, a deadline or a break, 3 AM is the point. Seeing the time left helps you pace yourself.

People set alarms for 3 AM, but an alarm does not show how long is left. The countdown does. It lets you see the time shrink and decide how to spend what remains.

If your device sleeps, the page catches up when it wakes. The time to 3 AM is always taken from your clock.

A bookmark is all you need to come back to this count. The page opens with the right figure for 3 AM, and the Share button passes it on to others.

Counting down to 3 AM can calm a restless night. Seeing exactly how long remains is often easier than guessing, and it lets you decide whether to get up or try to sleep on.

A different city gives a different answer. The picker recalculates the count for wherever you choose.
