LMP Calculator 101: How One Simple Date Does All the Heavy Lifting

You might be wondering – how can a single tool tell you so much?

Well, that’s where all the magic lies in. The LMP calculator takes the first day of your last menstrual period (LMP) and adds 280 days (or 40 weeks) to give you an estimated due date.

The calculation also assumes a regular 28-day period cycle, with ovulation occuring around Day 14.

Here’s how the LMP calculator helps you figure out the estimated due date in seconds:

  • Enter the first day your last period started: You can start by entering the first day of your last menstrual period. For example, if your last period started on May 1, that’s probably your LMP.

  • Let the calculator do the math: The tool automatically adds 280 days (40 weeks) to your LMP, which is the average length of a full-term pregnancy considering a regular 28-day period cycle and ovulation on Day 14.

  • Get your estimated due date: Within seconds, the LMP calculator displays your estimated due date along with which trimester you are in and the current week of your pregnancy.
