Halloween lands on October 31 every year, a date rooted in the ancient festival of All Hallows' Eve — the night before All Saints' Day on November 1. This tool tracks the whole days between your chosen date and the next October 31, plus the weekday it falls on, so costume orders, candy runs, and party invites go out with time to spare. Retailers and neighborhoods treat late September through October as prep season, and this counter is built to be checked throughout that whole stretch.
Starting from October 1, 2026, the counter reads 30 days to go, with Halloween itself landing on Saturday, October 31, 2026 — a weekend date that typically means bigger trick-or-treat turnout and later parties.
Costume stores and pop-up shops usually see their inventory peak in the final two weeks before the 31st, so a days-to-go figure under 14 is the usual cue to lock in sizes before popular options sell out.
Why is Halloween always on October 31?
The date comes from All Hallows' Eve, the evening before the Christian feast of All Saints' Day on November 1. Unlike movable holidays, it has never shifted to a particular weekday or week — it is fixed to the calendar date itself.
Is Halloween a federal holiday?
No. Halloween is a cultural and commercial observance in the US, not a federal or bank holiday, so schools, offices, and mail service run as normal regardless of what day of the week it falls on.
When should I buy a costume to avoid sellouts?
Aim for at least two to three weeks before October 31. Popular character costumes and children's sizes are the first to sell out as the days-to-go count drops into the single digits.
What is the connection between Halloween and All Saints' Day?
Halloween (October 31) is literally the "eve" of All Hallows', an older name for All Saints' Day (November 1). The trio is completed by All Souls' Day on November 2, together forming a three-day observance.
