How to use it

1. Open the file and go to Cycle Log.
2. Type the start date of your last few periods, plus end dates if you know them. Three to six cycles give useful averages.
3. Open the Dashboard to see today’s cycle day, your next period with a countdown and a likely start range based on your shortest and longest recent cycles.

Formula cells are locked so nothing breaks, and the sheets are protected without a password, so you can still adjust the design.
