mosque Calculated to Shariah-compliant formulas

Every Islamic calculator on CalcaTools uses formulas from recognised Shariah authorities — the Hilal Committee's Hijri conversion tables, the MWL/ISNA/Umm al-Qura prayer-time methods, the four-school consensus for Zakat Nisab, and the Faraid distribution rules from classical fiqh. The exact authority is cited on every tool page.

menu_book Sunni & Shia rules side by side

For tools where the calculation differs between schools (Faraid inheritance, certain Zakat triggers, prayer-time conventions), we surface the choice as a selector and document the difference in the methodology block. Pick the school that matches your tradition — the answer adjusts.

savings Zakat with the live Nisab

Zakat tools fetch the current spot gold/silver price (or let you enter your local rate) so the Nisab threshold reflects today's value, not a stale figure from last year. The 2.5% rate is the standard hawl-based calculation; agricultural Zakat (1/10 or 1/20) is available on the dedicated Ushr calculator.

verified For guidance, not a fatwa

These calculators give you the number — they do not give a fatwa. For complex personal situations (inheritance with revoked rights, mixed-asset Zakat, late prayer makeup rules), please confirm with a qualified scholar in your tradition. We're here to help with the arithmetic, not to replace your local imam.

Formula & methodology

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

  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?
WHO and UNICEF recommend exclusive breastfeeding for the first 6 months, then continued breastfeeding alongside solid food up to 2 years or beyond. Enter your baby's birth date above to get each date for your child.
How long is the breastfeeding period in Islam?
The Quran (2:233) sets the full term of nursing (rada'ah) at two complete lunar years — about 708–709 days, roughly three weeks shorter than two Gregorian years. Weaning earlier is permitted by mutual consultation of the parents.
When should my baby start solid foods?
From 6 months, while breastfeeding continues. Before 6 months a healthy baby needs only breast milk; after 6 months milk alone no longer covers iron and energy needs.
Why is the Islamic two-year term shorter than the WHO one?
Islamic law counts lunar (Hijri) years of about 354.4 days, so two lunar years are roughly 709 days, while two Gregorian years are 730–731 days — a difference of about three weeks.
Does this calculator replace medical advice?
No. It applies the WHO timeline and the classical fiqh term mathematically. Growth, allergies, and weaning readiness vary per child — always follow your pediatrician's guidance.
