I’m re-reading The Grand Illusion, before I dive into Premier. I think I’ve got the calendar figured out, 4 seasons, 2 months for each, and I’m guessing 36 days per month. One thing I’ve kinda tripped on is the length of a minute/day. 18 bells, in 3 sets of 6, I’ve assumed the repeating theme of 3’s is from Trinitarian theology, but I feel like either there’s more than 60 minutes in a bell, or the minutes are longer. I was leaning toward 90 minutes (or units, what you will) in a bell, as it makes the division in thirds easy. So I guess my question would be how long are the minutes or bells in The Grand Illusion?

You got the structure right. The days and the years are shorter than ours.
