Why is the tax year end 5th April?
Once a upon a time someone invented the clock.
For years we had been using the sun to tell the time –
Midday when the sun was highest in the sky each day
Midsummer when it was the highest in the sky in the year
Summer and winter solstice being highest and lowest points of the year
We split up the day and years with the help of sundials
Small ones like you see in the garden or big ones such as Stonehenge.
The inventors of the clock thought they could help people tell the time
– it would be especially useful when the sun was not out such as rainy days or at night
This worked very well for years – until someone noticed
that the clocks were no longer matching the sun
Investigations ensued to find out why
And then a solution needed to be found
And corrections made
The sun year, based on the earth’s orbit around the sun, is 365.2422 days long (365 days, 5 hours, 48 minutes and 46 seconds)
The human created calendar is exactly 365 days long
Add in extra day(s) in February
E.g. one every 4 years – hence 29th February
But this is not quite accurate enough
You also need to leave one out about every 100 years
Roman calendars had eleven months of 29 or 31 days, plus February with 28 days or 23 days if a thirteenth month of 27 or 28 days were added to try to keep in line with the solar calendar. All very
