Common mistakes

Assuming every month has one. Most months don't — a year typically has only one to three Friday the 13ths in total.
Mixing up months and dates. The date must be the 13th specifically; a Friday landing on any other day of the month doesn't count — check the day of the week calculator if you just need a date's weekday.

Frequently asked questions

How many Friday the 13ths happen in a year?+

Every calendar year has at least one Friday the 13th, and can have as many as three.

Why is Friday the 13th considered unlucky?+

The superstition combines two older fears — the number 13 and Friday as an unlucky day — that merged in Western folklore, especially popularized in the 19th and 20th centuries.

Can two Friday the 13ths happen in the same month?+

No — since a Friday the 13th requires the 13th of that specific month to land on a Friday, there can only be one per calendar month.

When is the next Friday the 13th?+

Enter any date above and this calculator scans forward to find the next month whose 13th falls on a Friday, along with exactly how many days away it is.
