Formula & methodology

Formula: Exclusive = birth + 6 months; WHO term = birth + 24 months; rada'ah = birth + 24 lunar months (= 708-709 days)

The Breastfeeding Period Calculator is built on a well-established calculation method. It uses the formula Exclusive = birth + 6 months; WHO term = birth + 24 months; rada'ah = birth + 24 lunar months (= 708-709 days) to turn your inputs into a reliable result. Turns your baby's birth date into every weaning milestone: exclusive breastfeeding to 6 months, solids from 6 months, the WHO 2-year mark, and the Islamic rada'ah term of two complete lunar years (about 709 days), with The steps are shown on the page so you can follow the reasoning from input to output.

  1. Enter the baby's date of birth.
  2. Pick a weaning plan — the Islamic rada'ah term (two lunar years), the WHO two-year benchmark, or a custom age in months.
  3. The calculator adds 6 Gregorian months for the exclusive-feeding window, 24 Gregorian months for the WHO mark, and 24 tabular Hijri months (≈ 709 days) for rada'ah.
  4. If the baby is already born, it shows today's age and percentage progress toward your chosen weaning date.

Frequently asked questions

How long should I breastfeed my baby?
Health organizations recommend exclusive breastfeeding for about the first 6 months, then continued breastfeeding alongside solids up to 2 years or beyond. Enter your baby's birth date and the tool maps these milestones for you: the 6-month exclusivity mark, the WHO two-year recommendation, and the Islamic rada'ah period of 24 lunar months.
How long is the breastfeeding period in Islam?
Islamic law recognizes the rada'ah period as two full lunar years, about 708–709 days, based on Quran 2:233, which says mothers may nurse for two complete years. This lunar-year span matters for rulings on foster relationships (rada'ah ties). The calculator converts your baby's birth date into both the Gregorian 24-month mark and the exact 24-lunar-month date.
When should my baby start solid foods?
The Breastfeeding Period Calculator is free, private, and accurate: it runs entirely in your browser (no uploads, no accounts), applies the standard calculation, and explains each step so you can verify the result. Turns your baby's birth date into every weaning milestone: exclusive breastfeeding to 6 months, solids from 6 months, the WHO 2-year mark, and the Islamic rada'ah term of two complete lunar years (about 709 days), with live progress tracking. There is no limit on usage, and it works on any device.
Why is the Islamic two-year term shorter than the WHO one?
The Islamic rada'ah period of two years uses LUNAR years (about 708–709 days, roughly 23.3 Gregorian months), while the WHO's two-year recommendation uses solar (Gregorian) years — a full 24 months. The difference is about three weeks. Both describe the same guidance: around two years of breastfeeding; they simply count years differently.
Does this calculator replace medical advice?
No — the calculator only maps dates onto the standard breastfeeding milestones (6 months exclusive, 24 months total, and the 24-lunar-month rada'ah period). Breastfeeding decisions should follow pediatric guidance tailored to you and your baby: milk supply, weight gain, and health conditions all matter more than any date. Use the milestones for planning, and consult your doctor for feeding decisions.
Why are there two different two-year marks?
The WHO recommends breastfeeding up to 2 years — 24 Gregorian months — while the Islamic rada'ah term is two complete lunar years, about 709 days, roughly three weeks shorter. Both are computed from the same birth date so families following either or both guidelines see each milestone. Close, but not identical.
What happens at the 6-month mark?
Two things: exclusive breastfeeding (no other food or drink) runs from birth to 6 months, and complementary solids begin around 6 months while breastfeeding continues. Both the end of exclusivity and the start of solids are marked. WHO guidance stresses continuing breastfeeding alongside solids, not replacing it.
How is progress toward a milestone shown?
As elapsed versus remaining time from the birth date to each milestone — e.g., “4 of 6 months of exclusive breastfeeding complete” — updating from today's date as a live tracker. Useful for pediatrician visits and planning the weaning transition.
Do premature babies use the same milestones?
Adjusted age is often used — milestones counted from the due date rather than the birth date, especially in the early months. The calculation works from whatever birth date is given, so the due date can be entered instead if the pediatrician advises adjusted age. A doctor's guidance always outweighs any calculator.
