The date of my last menstruation is June 2 1 of the lunar calendar. When is my due date?

The last menstrual period was 20 10 on June 2 1 0. I looked at the solar calendar for you. It's August of 20 10 1. If your menstrual cycle is normal, then the last menstrual period MINUS 3, plus 7 days, is the expected date of delivery. In other words, your due date is May 8th, 20 10. Good luck with your pregnancy
