‘Mathy’ Dates Throughout the Year

Did you waltz out the old year on December 31, 2023?

No matter what you did on 12,31,23, there are plenty of dates with mathematical significance to celebrate in 2024.

Take Pi day for instance, on 3/14 of any year. The actual number never ends, but we can still enjoy a tasty treat on March 14th at 1:59. Whether you like pi or pie, March 14th is a day to celebrate ~ erm ~ depending on how your country writes the date.

For those using the dd/mm/yy format – Pi day is September 22nd, or 22/7. If you teach in the US, invite your students to grab a calculator and figure out why Sept 22nd is Pi day in those countries. This page uses the mm/dd/yy format.

Some Dates are Mathier than Others

There are several mathematical dates sprinkled throughout the calendar. Some occur yearly and some every century or so, but all of them are worth a look.

April  will make a huge mathematical splash in 2024 ~ several days in April will be palindromes. April 2nd, (4/2/24), April, 20th, (4/20/24) and more!

In addition to all the “palin-dates” there will be an eclipse in North America on April 8th! Get your students ready to view this eclipse – in person or online.
