The Kalends were always the first day of the month.
The Nones were usually the 5th but sometimes the 7th, and the Ides were the 15th but sometimes the 13th.
At that time a pontifex (priest) was assigned to observe the sky.
When he first sighted a thin lunar crescent he called out that there was a new moon and declared the next month had started.
On these days the day letter follows the holiday name, which is abbreviated in these calendars.
These holidays are explained in the write-up for each day.
Originally, the month and the markers were based on the moon.
That’s because it spanned more than two lunar phases, starting from the day after full moon and continuing thru its last quarter and waning period, then past the dark new moon until another lunar crescent was sighted. It was dedicated to Juno, a principal goddess of the Roman Pantheon.
The Romans enjoyed more holidays than the number of our holidays and weekends combined. One of the hallmarks of progress seems to be that the populace is always made to work longer and, on top of it all, they are taxed more.
The Romans did not have weekdays in the same sense as our Monday, Tuesday, etc., however, they did have a defined markers within each month.
Some calendars were carved in marble or stone, but many were painted on walls for decoration.
Different geographical areas often held different gods in special esteem, and this led to regional variations in calendars. E., Romans modified their method of marking time to keep it in phase with seasons, but not require intercalation of an extra month. Month lengths were extended to bring the calendar’s total to 365 days, making it truly solar.
