When is Lammas anyhow? Though usually observed on August 1, I recently learned that August 6 is known as “Old Lammas.” I think that might be because the midway point between solstice and equinox tends to fall on this day, though technically this year it’s on August 7 at 9:05 AM, Central Time. Further complicating matters is the old tradition of beginning a holiday observance at sundown the night before, which means you could get started as early as July 31.
As for me, I got started even earlier than that, working on this essay: “How Lammas Changed My Life.” Please give it a read.
The confusion of dates should really present no problem. It allows a full week to celebrate. Keep trying until you get it right!
