Philocalian Calendar

The Philocalian Calendar, also known as the Chronography of 354, is a Roman almanac compiled in 354 CE. It is one of the earliest surviving documents to list Christian martyrs and festivals, and it also includes a list of Roman consuls and emperors. The calendar is a valuable source of information for understanding the religious and political landscape of 4th-century Rome.12

An almanac is a book or table containing a calendar of days, weeks, and months, along with astronomical data, climate information, and seasonal advice. Historically, almanacs have served as practical guides for farmers and as sources of entertainment and instruction.2
