Days Until Halloween Calculator
Count down to 31 October — days, weeks, sleeps and the weekday Halloween falls on this year, plus when to start carving and buying candy.
How it works
Days = 31 October (this year, or next if it has passed) − today
Halloween is fixed on 31 October, so the countdown only depends on today’s date. A carved pumpkin lasts three to five days before it sags, so carve on the 28th or later; uncut pumpkins keep for weeks on a cool porch. Candy sales peak in the final week — buying earlier avoids empty shelves, if you can resist eating it.
Worked example
From 26 September: 35 days, exactly 5 weeks.
