How Many Days Until Halloween? Date, Weekday and Countdown

Updated September 20, 2026 · 1 min read

Quick answer: Halloween is always on October 31. In 2026 it falls on a Saturday. Use the days until calculator for the exact number of days left from today.

Which day of the week is Halloween?

The date never changes, but the weekday moves forward by one each year, or by two after a leap year. That matters for planning parties and trick-or-treating, since Halloween on a school night feels different from Halloween on a weekend.

Where Halloween comes from

The name is a shortened form of "All Hallows' Eve", the evening before All Saints' Day on November 1. Many historians also link its traditions to Samhain, an older Celtic festival that marked the end of the harvest season. Trick-or-treating became widespread in North America during the 20th century.

Counting down

The days until calculator has a Halloween option that counts from today's date. If you want to plan backwards, use the days between dates calculator, for example to see how many weeks you have to finish a costume.

Trick-or-treat timing

Hours are set by each town, and some communities hold trick-or-treating on a nearby weekend day if October 31 falls on a weekday. Check your local council or community page.

Other autumn dates

The clocks change soon after Halloween. See our guide to when daylight saving time ends, and our guide to when Thanksgiving falls.
