How the Halloween weekday changes

Halloween always falls on October 31, but the weekday changes as the Gregorian calendar advances from one year to the next. Common years contain 365 days, while leap years contain 366 days. Because October 31 occurs after February, the additional day in a leap year affects the weekday on which Halloween falls.

Under Gregorian calendar rules, most years divisible by four are leap years. However, century years must also be divisible by 400 to qualify. For this reason, 2100 is a common year rather than a leap year.

This calendar contains 101 Halloween dates, beginning with Saturday, October 31, 2026, and ending with Thursday, October 31, 2126.
