The count above runs to 00:00 on 31 October in your own time zone, the moment Halloween begins, and it finds the next one by itself every year.

Halloween happens in the evening, and midnight is not when anyone means. Trick-or-treating starts around dusk, which in late October is somewhere near six. The page counts to the start of the day because that is the only moment that does not depend on where you live, but if the evening is what you are waiting for, put 31 October at 18:00 in the box and the count moves to it.

The date is fixed and the weekday is not, so Halloween lands on a different day of the week each year. When it falls midweek, parties tend to move to the weekend before, and the working days figure below the clock tells you how many school or work days stand between now and then.

Día de Muertos follows on 1 and 2 November. For that, or any other date, use the countdown.

How to use it

  1. Read the count at the top: days, hours, minutes and seconds, moving as you watch.
  2. Look below it for the same span as whole days, weeks and working days.
  3. Change the date in the box to count down to anything else instead.

Questions

Does it count to Halloween night?

To the start of 31 October, midnight. Halloween night is about eighteen hours later, and if that is the moment you want, set the box to 31 October at the hour trick-or-treating starts where you are. The page does not assume one, because dusk moves with latitude.

Is Halloween always on the 31st?

Yes, always 31 October, which is why its weekday moves from year to year. Some towns in the United States hold trick-or-treating on a nearby weekend evening when the 31st falls on a school night, but the date itself does not change.

What does it show on Halloween?

It counts up from midnight and tells you how long Halloween has been going, rather than skipping to next year. From 1 November it counts to the next one.

Which time zone is this counting in?

Yours, the one your device is set to. The target is midnight at the start of the day in your own local time, because that is when the day arrives where you are. A holiday reaches Kiribati about a day before it reaches Hawaii, and each of them sees their own count here rather than anybody else's.

Does it keep counting while I leave the tab open?

Yes, it ticks once a second for as long as the page is open, and picks the count back up from the clock when you return to the tab. Nothing is stored between visits, so opening it again simply asks your clock what time it is now.

Is any of this sent anywhere?

No. The arithmetic runs in WebAssembly inside this tab, and the only thing it reads is your device clock. There is no account, no cookie of ours and no record of what you looked up. Load the page once and it keeps working with the network off.

The same question, other days

Each of these counts to the start of its own day, in your time zone, with the same live seconds and the same working days figure.

Your data stays on your device

Everything above runs inside your browser as WebAssembly compiled from Rust. Nothing you type is uploaded, logged or stored on a server. You can load this page once, go offline, and it still works.

This page makes no requests at all, to anywhere. That is not a promise in the copy: it is a Content-Security-Policy header your browser enforces, and connect-src on it is none. Open the network tab and watch nothing happen.
