This is a list of calendars, dating systems, chronologies, etc. used in Magic: The Gathering.
Dominaria
Argivian Reckoning
Argivian Reckoning (AR) is the primary calendar used on Dominaria (notably excepting the continent of Corondor). It sets year 0 as the year in which both Urza and Mishra were born. It only came into use many years after the time of the Brothers, and was used informally for several thousand years before an attempt was made to clarify historical facts. It is named after New Argive, a country famed for its scholars. The last time the date was explicitly mentioned or could be directly derived from the storyline (Odyssey), it was 4306 AR. With the advent of Time Spiral block, the date can be gleaned as around 4505 AR, supposing that Argivian Reckoning is still in use.
Common Era
Common Era (CE) is a dating system established by New Sumifans in Almaaz. It starts around 3035 AR[1].
Penregon Founding
Penregon Founding, or PF for short, is the only calender system known to be in use at the time of The Brothers' War. It sets Year 0 as the year Penregon, the capital of Argive, was founded. When Urza and Mishra were born (0 AR), the year was 912 PF.
Reckoning of the Sages of Minorad
The Reckoning of the Sages of Minorad is a calendar primarily used in Corondor. Year 1 in this reckoning begins on the anniversary of the gathering of the Sages of Minorad. It corresponds with the year 3000 of the Argivian Reckoning.
Ravnica
Ravnica uses the measure of Al Concordant and Zal Concordant. Al Concordant was used to measure the time before the signing of the Guildpact, while Zal Concordant was used afterwards.
