Menstrual cycles aren't a calculation, it's really just as simple as counting from the first day of your period up until the next period. You figure out the average over your last six cycles - anything up to a weeks variation from your average menstrual cycle is considered normal - but cycles can change, it's sometimes easier to use a menstrual tracking app on your phone to keep track for you.
It's not a menstrual "circle" - it's a menstrual cycle. And on another note, you can calculate the menstrual days by marking it down on your calander; from the first day you started.

This two information is needed in order for you to calculate your ovulation using an ovulation calculator. The date of your period is not enough information, to calculate ovulation.
An OBGYN typically calculates a woman's due date based on the first day of her last menstrual period (LMP) and the average length of her menstrual cycles. This method assumes that conception occurs about two weeks after the start of the menstrual cycle. The due date is calculated by adding 280 days (or 40 weeks) to the first day of the LMP.
