Lets have some leap year fun!
Did you know?
You do now!!!
So why does our calendar only sometimes features the 29th of February?
29th Feb
Leap Years always seem to creep up on us and there is actually some maths behind why our calendar only sometimes features the 29th of February.
For a bit of context, our current
calendar system was established
back in the sixteenth century.
Conceptualised by Pope Gregory
XIII in 1582, the consequently
named Gregorian calendar sought
to correct the previous system
which was gradually desynchronising with the seasons.
Julius Caesar was the first to
introduce the leap year over 2000
years ago as a remedy for the 365
day year, which has never quite
been perfect.
All the confusion boils down to the
earth’s rotation in relation to the
sun as well the fact that the earth
spins on an axis. If the earth rotated
at the exact same angle, there
would be no seasons and instead
just a consistent climate in different
parts of the world. If we had
continued with Julius Caesar’s
version of the calendar, the dates
would gradually desynchronise
meaning we could be having winter
weather in July (although it
technically could still happen…).
Henceforth came the leap year,
designed to add an additional day
for every year which can be divided
evenly by four with the exception of
centuries.
Other things that leap!
