What is Friday the 13th?

Friday the 13th is any Friday that falls on the 13th day of a month. In many Western countries it's considered an unlucky day, a superstition that took hold in the 19th and 20th centuries.

A month has a Friday the 13th exactly when it starts on a Sunday. Because of how the weekdays shift from month to month, every year has at least one Friday the 13th and at most three. In 2026 there are three: February 13, March 13 and November 13.

Tool description

The tool opens with this year and the next nine. Enter any other range of years, in either order, and it shows:

  • The next Friday the 13th from today, and how many days are left until it
  • How many Fridays the 13th fall in the range
  • A table of every Friday the 13th in the range, with its month and how far it is from today

The next Friday the 13th is highlighted in the table when it's in the range. The countdown shows "Today" on a Friday the 13th.

Examples

  • 2026: February 13, March 13 and November 13
  • 2027: only August 13
  • 2015: February 13, March 13 and November 13, the same months as 2026, because both are common years that start on a Thursday
