How long until 3:30 AM?

Why a clock time countdown is different

Most countdowns end on a date and stay there. This one resets, because 3:30 AM comes back every day at the same clock reading.

Crossing midnight or noon is where mental sums go wrong, and 3:30 AM is often close to one of them. The page counts in seconds from your clock, so the answer is right at any hour.

Your local clock decides which 3:30 AM is next. A note under the number tells you when the target is tomorrow.

The minutes and seconds in the tiles are the same wait as the main display, just in smaller units. Use whichever one suits the job, whether that is boiling an egg or catching a bus.

At the start the bar is empty, and by the next 3:30 AM it is full. The figure under it says how far along you are.

At most a day separates you from 3:30 AM, and often much less. The number on the page falls from a high point just after the moment passes to zero when it arrives.

Working across time zones

The world has many versions of 3:30 AM. This page shows yours and compares it with a handful of others.

Use the table to agree a deadline that is fair to everyone. A cut-off at 3:30 AM in one city can land at an awkward hour elsewhere.

Clock changes move the gaps between cities. The US and Europe switch on different dates, so 3:30 AM can shift for a few weeks.

Your zone is set by your device and not by us. The count therefore matches your own watch. Use the picker for a colleague's city or a place you plan to visit.

Using the countdown

The distance to 3:30 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.

Some watch for 3:30 AM to finish work, others to start. Either way, a countdown saves doing the sum.

A countdown to 3:30 AM suits any routine built around a fixed hour. Think of a school bell, a bus, a call or a closing time. You see the wait at a glance and plan the rest of your day around it.

Come back to the tab at any time. The figure refreshes the instant the page is in view again.

No sign up or app is needed. Open the page, read the time left to 3:30 AM, and close it again. Nothing is stored about you, and the count is worked out in your browser.

For shift workers, 3:30 AM can mark the start of sleep or the end of it. The tiles show the minutes left, which makes it easier to judge whether a short rest is worth taking.

Pick a city and the time left to 3:30 AM is recalculated for it. Pick another to compare.
