Gary Gygax put something like this in 1E. I think it’s that one day goes by in the game-world for every day spent not playing in the real world. I never used that because it always seemed kind of meta to me.I use the Midgard setting optional rules. For each week that passes IRL the players get double that in downtime.
So if it takes you 4 sessions over 4 weeks once it's over the PCs get 2 months of downtime.
An exception would be if you wanted the next adventure to be hot on the heels of the last one.
How does that play out at (or away from) the table? It sounds like you have an adventure that everyone is committed to finishing before they can use their accumulated downtime. Is that right, or could a character leave off adventuring and have a period of downtime that’s staggered from that of the other characters?
