Major Longsol
The longest solar day of the year, noon to noon.
The Sun is falling behind the clock at its fastest.
The name
Names ending in -sol describe the length of the solar day, noon to noon. Major and Minor tell the two peaks apart by size.
Precision
A flat peak: the value barely changes for days on either side, so the exact hour means little.

Every year
Between 1900 and 2100 it comes as early as December 21 at 23:58 UTC (2096) and as late as December 23 at 21:41 UTC (1903).Dates wobble through each four-year leap cycle and creep earlier across a century, until a skipped leap day, as in 1900 and 2100, sets them back.
