How it works
How to Calculate Your Due Date
Your estimated due date (EDD) is calculated based on the first day of your last menstrual period (LMP). The most common method, known as Naegele's rule, adds 280 days (40 weeks) to your LMP date.
By Last Period
The most common method. Enter the first day of your last menstrual period and we add 280 days.
By Conception Date
If you know when you conceived, we add 266 days from that date for your due date.
By Ultrasound
Enter your ultrasound date and gestational age for the most accurate calculation.
Pregnancy Care in South Africa
South Africa offers both public and private antenatal care. In the public sector, you can register at your nearest clinic for free antenatal services. Private care through a gynaecologist or obstetrician is covered by most medical aids as a Prescribed Minimum Benefit (PMB) condition.
Key tests during pregnancy in South Africa include HIV testing (offered routinely at the first visit), syphilis screening, blood group testing, and glucose tolerance testing around 26-28 weeks. Your healthcare provider will guide you through the recommended schedule of visits and scans.

Frequently Asked Questions
Your due date is estimated by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP). This is known as Naegele's rule. If you know your conception date, we add 266 days instead. Your healthcare provider may adjust this based on ultrasound measurements.
A due date calculator provides an estimate. Only about 5% of babies are born on their exact due date. Most babies arrive within two weeks before or after the estimated date. An early ultrasound (before 12 weeks) provides the most accurate dating.
In South Africa, you should book your first antenatal visit as soon as you know you're pregnant, ideally before 12 weeks. If using the public healthcare system, register at your nearest clinic. For private care, schedule an appointment with a gynaecologist or obstetrician.
Under the Basic Conditions of Employment Act (BCEA), you are entitled to 4 consecutive months (121 days) of maternity leave. You can start leave up to 4 weeks before your due date. You may also claim UIF maternity benefits of up to 66% of your salary.
Yes. The standard calculation assumes a 28-day cycle. If your cycle is longer or shorter, your ovulation date shifts, which affects your due date. Our calculator allows you to adjust for your cycle length for a more accurate estimate.
Yes. If an early ultrasound shows a significant difference (more than 7 days) from the LMP-calculated due date, your healthcare provider may adjust your due date based on the ultrasound measurements. Earlier ultrasounds are more accurate for dating.
