Here’s the historical data on their RD release dates in recent years:
2024: March 22nd, between 3-3:30pm PST
2023: March 17th between 3-3:30pm PST
2022: Friday, March 18th, between 3-3:30pm PST
2021: March 19th between 3:3-4pm PST
2020: March 19th 3:15pm PST
So that’s RDs released on Friday four times (2024, 2023, 2022, 2021), and only once on a Thursday (in weird March 2020.) Almost all were in the 3rd week in March (except 2024, which was the 4th week but only because of how the calendar fell).
My prediction, given their history of Friday releases, the most likely date is this Friday, March 21st at approximately 3:15pm. Which makes sense, because Claremont McKenna already announced that its RDs will be released on March 21st at 5pm.
