How do Freemasons measure time? What do all those abbreviations mean before those strange
looking years that do not match our popular calendar? This post will introduce you to the Masonic measurement of time. When you are finished reading this, you will be able to decipher the hidden meaning in Masonic calendars.
Symbolic Lodge: First, let’s deal with the Symbolic Lodge (Blue Lodge) which covers the first three degrees of Freemasonry and is the foundation upon which everything else is built. On your lodge notice or Trestleboard you will see the current year listed as A.L. 6008. What does the A.L. stand for?
A.L. is a latin abbreviation for Anno Lucis, meaning “in the year of light.” This system of calendar time measures the current year from the creation of the world from the dating used by Archbishop Usher, minus four years. Just add 4000 to the current calendar year to arrive at the correct A.L. year (e.g. 2008+4000=A.L. 6008).1
Royal Arch Masons: Royal Arch Masons begin their time measurement from the year Zerubbabel began building the Second Temple (530 BC), calling it Anno Inventionis (A.I.), meaning “in the year of the discovery.” Add 530 to the current calendar year to get the A.I. year (e.g. 2008+530=A.I. 2538).2
Royal and Select Masters: This calendar year is calculated from the completion of King Solomon’s Temple and is called Anno Depositionis (A.Dep.), meaning “in the year of the deposit.” Add 1000 years to the current calendar year to get the A. Dep. year (e.g. 2008+1000=A. Dep.3008).3
Knights Templar: The Masonic Knights Templar begin counting time from the creation of their Order in 1118 AD, calling it Anno Ordinis (A.O.) meaning, “in the year of the Order.” Subtract 1118 from the current calendar year to arrive at the A.O. year (e.g. 2008-1118=A.O. 890).4
Scottish Rite: The Scottish Rite calendar follows the Hebrew calendar and is known as Anno Mundi, meaning “in the year of the world.” The Hebrew calendar is a lunar calendar and has two annual starting points. The ecclesiastical year beings in the month Nisan (new moon following vernal equinox) while the civil year begins in the month Tishri (new moon after autumnal equinox). To find the Jewish year, just add 3760 to the common calendar in the month of September (e.g. 2008+3760=A.M. 5768). So, Setpember 1, 2008 through August 31, 2009 is A.M. 5768.5 6
