Easy ways to calculate your cycle days

I usually just set into my calendar in my phone for the past years. Recently bump into Sis Irtiyah’s way of jotting down in easy way and i transferred all the data from the phone in to the excel and yes… its really2 easy to calculate your cycles days. Done redo the listing for the year 2010. Just realized that my cycle days are vary each month.

Still thinking whether need to track back all the previous years record.

Try it now gals.
