In-game weeks are 6 days long. 9 in-game days pass for each real-life week (currently), although within a campaign it will move at a rate determined by the GM.
Campaigns may or may not begin on the posted in-game date; ask your GM for the in-game start date of a long-term campaign you are in, or check the adventure writeups.
If you are a GM attempting to find a game date for a session you ran between Saturdays, just approximate a date between the two listed ones. Exact math isn't necessary.
