Due Date Calculator
Get ready for baby's arrival — estimate your due date, see exactly how far along you are today, and keep track of the pregnancy milestones ahead.
Calculate from
The first day of bleeding, not the last.
We adjust the estimate for longer or shorter cycles.
Only about 4% of babies arrive exactly on their due date — most are born within two weeks either side. Your dating scan gives the most accurate estimate. Book your antenatal visit with Dr Chaminda Mathota.
