If anyone is interested, here's a comparison between the 2020 and 2024 Olympics (for sailing/surfing I went with their original schedule). The colored squares was the 2020 schedule (blue = qualification only days, gold = medal days) while squares with a letter (Q for qualification only days, F for finals days) is the 2024 schedule.
Most sports either stayed the same or shifted one day, but there are some major changes like taekwondo shifting from the first four days to days 11-15.
