EDD Calculator Singapore

Wondering how far along you are and when your baby might arrive? Our pregnancy calculator estimates your estimated due date using the same principles clinicians rely on. It helps you plan antenatal appointments, track milestones, and prepare for the weeks ahead with greater confidence. 

One of the first things most newly expecting parents want to know is when the baby is due. With this handy tool, calculating your baby's date of birth is a breeze. Let our tool help you calculate your baby’s expected birthday!

Understanding Your Estimated Due Date
Your estimated due date (EDD) is the projected day your baby may be born, typically 40 weeks from the first day of your last menstrual period (LMP). It is a guide rather than a promise; only a small proportion of babies arrive exactly on that date.

Knowing your EDD supports timely antenatal care, helps you follow foetal development, and allows you to organise maternity leave and birth plans. It also informs the scheduling of key screenings and scans. A pregnancy calculator or pregnancy due date calculator provides this timing quickly, but your clinician may refine it.

How the EDD is set can vary. Factors include the regularity and length of your cycle, how certain you are of your LMP or conception date, and measurements from early ultrasound scans. Medical considerations, assisted conception, and multiple pregnancy may prompt your clinician to refine the date. Calculators cannot predict the exact day of birth, and not all pregnancies last precisely 40 weeks. Many babies arrive between 37 and 42 weeks. Irregular cycles do not make calculators pointless—they still offer a helpful estimate, though an early ultrasound can improve accuracy. A pregnancy due date calculator provides a starting point that your clinician can verify.

Always check in with your healthcare professional if you have any questions.
