CALENDAR


Currently there’s artistically nothing noteworthy planned. But, since I don’t want it for you to be a waste that you clicked on the link to this page: Did you know that the word calendar comes from the Latin calendarium, which literally means debt book or account book?
   No? Let me explain…



Calendae (also Kalendae, derived from calare: to announce solemnly, call out)
  1. The first day of the month;
  2. (literally) ‘proclamation day’: at the Calends (Kalends) it was announced whether the Nonae would take place on the 5th day or on the 7th day of the month.
Nonae

Idus (plural Ides)
  1. The 15th day of March (Martius), May (Maius), July (Quintilis), and October; or the 13th day of the other months;
  2. the deadline for payment and cancellation period for loans.

It seems that Seneca is the one who created the calendarium which means debt book or account book:

…There was one class of persons at Rome, to whom the Kalends of January was anything but a festival. The first day of the month was that on which the creditor could demand his debt with the pawnbroking interest of one per cent. for the month, i. e., 12 per cent. per annum, and the Kalends of January would be doubly dreaded as the first of the year as well as the month. The calendarium was the book in which the usurer inscribed a list of the names of his debtors, and the amount of their debts. “He who has a great calendarium” says Seneca, “is a rich man.”…

The Roman Calendar had 10 months of 304 days in total; the remaining days were not assigned to any month:
