Solar year
The June solstice solar year is the solar year based on the June solstice. It is thus the length of time between adjacent June solstices.
In 6000 BC, the December solstice solar year had a length of 50:35 in excess of 365 days and 5 hours. This shortened to 47:55 in 2000 AD. It will remain between 47:45 and 48:00 at least until 10000 AD.
