If you are able to make relatively few commitments for a month, go to sleep when you feel tired. Sleep as much as feels good. Track it in a spreadsheet.

Some people with non-24 have very regular sleep/wake cycles. I'm not as fortunate, but in the winter will tend towards 24-29 hour days, with an average just over 27 (perhaps this winter has even been a little under 27 as I've been more physically active)

In the summer it's close enough to 24 hours that I can stick to a 24-hour schedule most of the time.

Interesting I’ll have to track it a bit. I’ve always adjusted a bit in winter but never thought to measure / optimize it.
