Geocache Description:

29 February 2020, 11:00 - 12:00

Everyone knows a year lasts 365 days. The number is right on your calendar — except during leap years when you get an annoying reminder that the 365-day year doesn’t quite match up with the true year, as defined by how long it takes the Earth to complete one orbit around the sun.

Forcing the human calendar to stay in sync with nature’s cycles requires some awkward contortions. Every four years, February has 29 days instead of the usual 28. So, 2020 will be a 366-day year. But if a year is divisible by 100, there’s no extra day — unless the year is divisible by 400, in which case there is an extra day after all. In other words, 2100 will not be a leap year, but 2400 will.

It’s all a bit of a mess, but it’s necessary.



Come and join us for a chit-chat and laughter and earn your Leap Day souvenir.

We look forward to seeing you there!
