Home › Due Date Calculator
Free pregnancy due date calculator. Estimate your baby's due date based on last menstrual period or conception date.
The due date calculator estimates a pregnancy's expected delivery date from the first day of the last menstrual period or the date of conception. It also marks trimester transitions and major prenatal milestones.
Expecting parents, midwives, doulas, and family members helping plan around the arrival. It is also useful for OB-GYN appointment scheduling and for tracking how far along a pregnancy is week by week.
It replaces fuzzy "around early November" estimates with a specific date and a calendar of trimester milestones. It also helps coordinate appointments, leave from work, and preparations.
It answers questions like "When is my baby's estimated due date?", "What week of pregnancy am I in today?", and "When does the second trimester begin based on my last menstrual period?"
