What Is the Masonic Calendar? Anno Lucis (A.L.) and the “Year of Light” Explained
Share
When people search for the “Masonic calendar,” they usually mean Anno Lucis (A.L.), the “Year of Light” dating convention. In a common modern calculation, 4,000 is added to the Common Era year, so 2026 becomes A.L. 6026.
That simple formula is useful, but the history is more complicated than “Freemasons have a secret calendar.” Masonic bodies have used several ceremonial dating systems, practices vary, and ordinary lodge life still uses the normal civil calendar for practical dates.
What does Anno Lucis mean?
Anno Lucis is Latin for “in the Year of Light.” The phrase became associated with Masonic dating that places the symbolic beginning of the era about 4,000 years before the Common Era.
The Grand Lodge of British Columbia and Yukon’s historical material notes that older Masonic records were not perfectly consistent: early writers used “Year of Masonry,” “A.L.,” “Year of the World,” and dates based on different chronologies before the modern 4,000-year convention became familiar.
How do you calculate the Masonic year?
The common modern rule is:
Common Era year + 4,000 = Anno Lucis year.
For example, 2026 + 4,000 = 6026, so the year may be written as A.L. 6026.
This should be treated as a convention, not a historical claim that Freemasonry literally began in 4000 BCE. The British Columbia and Yukon historical resource specifically warns against reading the date as proof of Masonic antiquity.
Where might you see A.L. dates?
Anno Lucis can appear on ceremonial records, commemorative inscriptions, cornerstones, certificates, lodge documents, or historical Masonic material. It is not normally a replacement for the everyday Gregorian calendar used to schedule a lodge meeting, pay a bill, or book a room.
That distinction answers one recurring public question: the “Masonic calendar” is not simply a lodge fiscal year.
Do all Masonic bodies use the same calendar?
No. Different Masonic bodies have historically used different symbolic eras and abbreviations. Even within Craft Masonry, usage has changed over time and by jurisdiction.
That is why a list found online should not be treated as a universal rulebook. If you are interpreting a date on an old certificate, medal, cornerstone, or lodge document, identify the body and jurisdiction first.
Why is it called the Year of Light?
The phrase connects the dating system with the symbolism of light, knowledge, and beginnings. But historical research published through the Grand Lodge of British Columbia and Yukon shows that the terminology developed over time and should not be flattened into one neat origin story.

Is Anno Lucis connected to astronomy or the Moon?
There is no good basis for turning Anno Lucis into an astronomical or lunar theory. Current public discussion still produces speculative claims connecting the number 6026 with unrelated ancient events or celestial ideas. The documented Masonic history is simpler: it is a symbolic chronological convention with roots in older creation-era dating.
Is the Masonic year always exactly 4,000 years ahead?
That is the familiar modern Craft-Masonry convention, but historical documents show earlier variations, including 4,004-year calculations. If you are doing historical research, use the date as evidence that needs context rather than automatically subtracting 4,000 from every old Masonic inscription.
