The basic principle behind finding your conceived date based on birthday is simple math. A typical pregnancy lasts approximately 280 days (40 weeks) from the first day of your last menstrual period (LMP), or about 266 days (38 weeks) from the estimated date of ovulation. Therefore, we can estimate the conception date by subtracting 266 days from your birth date.
Here's the formula:
Conceived Date = Birthday - 266 days
Keep in mind that this is an estimation. Several factors can influence the actual conceived date, including:
- Menstrual Cycle Length: This calculation assumes a 28-day cycle. Shorter or longer cycles will affect the results.
- Gestation Period: Babies born before or after the average gestation period will have different conception dates.
