Sol-mōnaþ / Solmonath.. Month of Cake.

February 1st marks the beginning of Sol-mōnaþ (or Solmonath) 

In the old Angelo Saxon calendar Sol is the month between Gēola (January) and Hreð-monaþ (March). 

This is the Anglo-Saxon name for what we call February, translating to "month of the hearthcakes". While "sol" sometimes refers to mud, or even melting snow, in this context it signifies "hearthcake," these are cakes baked on a traditional hearth. 

This practice was recorded by the scholar Bede, it comes from a time when theses cakes where offered to the gods as thanks and to honor them

Sol also translates to Sun and could be considered Sun Month.

Not to be confused with Sol Month from the proposed  13 month international calendar 

A 13-month calendar, like the proposed International Fixed Calendar (Cotsworth Plan) by Moses B Cotsworth.

This plan divides the year into 13 months of exactly 28 days (four 7-day weeks), totaling 364 days, with an extra "year day" added annually and a leap day every four years, offering perpetual consistency where dates always fall on the same day of the week, though it requires adjustment for the solar year and faces challenges with the current 12-month system.
