What is milk-kinship (radaa) and why does this period matter for it?

Radaa is a marriage-prohibited relationship that can form between a nursing woman (and her close relatives) and a child she breastfeeds. Scholars set conditions, such as a minimum number of feeds and the child's age, for radaa to take legal effect — this calculator only computes the outer time boundary the Quran mentions.

Does breastfeeding after this 2-lunar-year period still establish milk-kinship?

Views differ — the majority position generally limits radaa's legal effect to nursing within or close to this period, but minority opinions and edge cases exist. This is a genuinely debated area of fiqh; consult a scholar for a definite ruling on a real milk-kinship question.

Does the Quran require exactly 2 full years of breastfeeding?

Quran 2:233 describes two complete years as the full term for those who wish to complete it — not a strict minimum every mother must reach. The same verse explicitly allows earlier weaning by mutual parental agreement.

Is early weaning sinful?

No — the verse explicitly permits weaning before 2 years if both parents mutually agree and no harm is intended to the child. This calculator's date marks the full/complete term, not an obligatory minimum.

Why does this use lunar (Hijri) months rather than solar months?

The Quran specifies "two complete years," and Islamic jurists computing exact durations from Quranic time periods generally use the Hijri lunar calendar, consistent with how this site's Iddah calculator handles its own Quranic periods.

Can this calculator be used to decide when to introduce solid foods?

No — this is a religious/legal reference date (relevant mainly to milk-kinship rulings), not medical or nutritional guidance. Follow your pediatrician's advice for actual infant feeding and weaning decisions.

Does this period affect a child's inheritance or lineage rights?

Milk-kinship (radaa) primarily affects marriage eligibility, not inheritance or biological lineage — a milk relationship doesn't create inheritance rights the way blood or marriage relationships do.

What if the biological mother isn't the one breastfeeding the child?

Radaa rulings can also apply to a wet nurse or any woman who breastfeeds the child under the recognized conditions — this calculator only needs the child's birth date and doesn't distinguish who is nursing.

About the Breastfeeding Period Calculator

Computes the end of the Quran's full breastfeeding period (2 lunar years) from a child's date of birth, relevant to milk-kinship (radaa) rulings.

100% Free Runs in Your Browser No Sign-Up Required

How to use it

Enter the child's date of birth.
The calculator adds 24 lunar (Hijri) months using the tabular Hijri calendar.
Read the computed end-of-breastfeeding-period date.
Treat the date as approximate — actual weaning is a personal, often gradual decision.

Formula

Birth date + 24 lunar (Hijri) months (Quran 2:233, "two complete years").

Worked example

A child born January 1, 2026 completes the 2-lunar-year period around December 10, 2027.

Interpreting your result

This period is most significant for milk-kinship (radaa) rulings — nursing within it can establish a marriage-prohibited relationship under conditions scholars specify. It is not medical advice on how long to breastfeed, and the same verse explicitly permits weaning earlier by mutual parental consent.

Recommendations

• Computed on the tabular Hijri calendar (same basis as this site's Hijri Date Converter) — treat the date as approximate, not exact to the day.

Frequently asked questions

No — it computes the Quran's legal/ritual reference period (relevant to milk-kinship rulings), not a medical recommendation. Follow your pediatrician's guidance for actual infant feeding decisions.
