If you bookmark the page you will always see the current gap rather than the number that was true on the day you saved it, and nobody has to edit anything for that to stay correct.

About Pi Day

A light-hearted maths celebration on 3/14, echoing the first digits of pi. Pi Day is a cultural observance rather than a legal holiday in most places, which means work and school schedules usually continue as normal, but shops, restaurants and event organizers often plan promotions and gatherings around it.

Pi Day is tied to a fixed calendar date, March 14, so the day of the week changes from year to year while the date itself does not.
