Why count sundays rather than days?

Sundays give the number of weekend days left, which is usually what matters for preparation, travel or shopping rather than working days.

How the count is worked out

Counting starts from tomorrow, not today, and includes Pi Day itself if it lands on a Sunday. That matters most when the event is close: a difference of one day at the start can change the total by a whole Sunday. 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.

Sundays 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:

Sundays by month

How the remaining sundays spread across the calendar between now and Pi Day:

MonthSundays
September 20261
October 20264
November 20265
December 20264
January 20275
February 20274
March 20272

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.
