How the count is worked out
Counting starts from tomorrow, not today, and includes Pi Day itself if it lands on a Friday. That matters most when the event is close: a difference of one day at the start can change the total by a whole Friday. Because weekdays repeat every seven days, the count is roughly the number of days remaining divided by seven, then rounded up or down depending on which weekday today is. Today is a Tuesday, and Pi Day falls on a Sunday.
Fridays until Pi Day in future years
The figure changes every year, because both the starting date and the weekday Pi Day falls on shift. Counted from the same point each year:
| Pi Day | Weekday | Fridays in the year before |
|---|---|---|
| March 14, 2027 | Sunday | 52 |
| March 14, 2028 | Tuesday | 52 |
| March 14, 2029 | Wednesday | 52 |
| March 14, 2030 | Thursday | 52 |
| March 14, 2031 | Friday | 53 |
Fridays by month
How the remaining fridays spread across the calendar between now and Pi Day:
| Month | Fridays |
|---|---|
| September 2026 | 1 |
| October 2026 | 5 |
| November 2026 | 4 |
| December 2026 | 4 |
| January 2027 | 5 |
| February 2027 | 4 |
| March 2027 | 2 |
Most months contain four of any given weekday, and some contain five. A month has five of a weekday whenever its length runs past the fourth occurrence, which is why the totals above are not evenly spread.
