    On this day, the Greeks made a libation to Artemis. Daughter of Zeus and Leto, sister of Apollo, she is the goddess of wild animals, hunting and warlike frenzy. She is also the protector of children (human and animals), pregnancy, childbirth and midwives. Her favor guarantees pure hunters and soldiers to be guided until their death which she will take. #mythology #myth #legend #calendar #9April #GreeceAncient #Artemis

Multicultural and multi-religious almanac

An almanac is a calendar showing the main dates of the calendar, the religious holidays, bearing ephemerides such as the phases of the moon or the duration of the days (lunar and solar calendars).

A calendar is a system for marking dates according to time. Such a system was invented by men to divide and organize time over long periods. The observation of the periodic phenomena of the environment in which they lived — such as the daily movement of the shadow, the return of the seasons or the lunar cycle — served as the first references for organizing the agricultural, social and religious life of societies.

The calendar used today in most of the world is the Gregorian calendar. In everyday language, an ephemeris designates what happens daily; the ephemeris of the day is the list of the significant events of this day.
