			| Interactive Tool: What Is Your Due Date?Skip to the navigationWhat does this tool help you learn?This interactive tool
		  calculates your pregnancy due date, an estimate of when you are likely to
		  deliver your baby. To find your due date, the calculator takes the
		  first day of your last menstrual period (LMP) and adds 40 weeks. If you are
		  planning a pregnancy, you can use this calculator to plan the birth for a
		  certain month or season. Katz VL (2008).
