How it is calculated
The next Friday the 13th after 10 October 2026 is 13 November 2026. The 13th of a month falls on a Friday whenever the month starts on a Sunday, which happens one to three times a year. The calculator lists the next dates from today or all dates in a year – and works for any weekday and day of the month, such as Tuesday the 13th or Friday the 17th.
Friday the 13th, 2026 to 2031
| Year | Friday the 13th |
|---|---|
| 2026 | 13 February, 13 March, 13 November |
| 2027 | 13 August |
| 2028 | 13 October |
| 2029 | 13 April, 13 July |
| 2030 | 13 September, 13 December |
| 2031 | 13 June |
2026 has three: February, March and November. February and March 2026 both start on a Sunday because February 2026 has exactly 28 days (4 weeks).
How often does Friday the 13th happen?
The Gregorian calendar repeats every 400 years: 400 years have 146,097 days, exactly 20,871 weeks. Counting all 4,800 months of that cycle gives the weekday of each 13th (calculated):
| 13th falls on | Times in 400 years |
|---|---|
| Monday | 685 |
| Tuesday | 685 |
| Wednesday | 687 |
| Thursday | 684 |
| Friday | 688 |
| Saturday | 684 |
| Sunday | 687 |
So the 13th lands on a Friday slightly more often than on any other weekday. Every single year has at least one Friday the 13th and never more than three.
How it is calculated
The calculator uses the Gregorian leap year rule of the U.S. Naval Observatory (USNO): a year divisible by 4 is a leap year, except century years not divisible by 400. The weekday comes from the Julian day number modulo 7, because 7-day weeks run on without a break. To see how many days are left until one date, use the countdown; to look up the weekday of any date, use the day of the week calculator.
