Enter the first day of your last period and Astra calculates your estimated due date, the zodiac sign your baby would have, the numerology vibration of that date and a few names that harmonize with it.
The estimated due date is calculated with Naegele's rule: 280 days (40 weeks) counted from the first day of your last menstrual period. If your cycle isn't 28 days, Astra adjusts the estimate. It's an approximation: only about 4% of babies are born exactly on their due date, and your healthcare provider can refine it with an ultrasound.
Because we love the cosmic side of names, Astra also shows you the zodiac sign for that date and its ruling number and planet in numerology —an interpretive tradition, not a science— to inspire you with names whose energy resonates with that day. Discover more in names by sign, the name numerology tool, or explore unique names.
Meaning, number and ruling planet of each name, straight to your WhatsApp.
