Common questions
Fasting explained.
Quick answers to the questions we hear most often.
When does the fast start and end each day?
The fast begins at Fajr (true dawn) — typically 60–90 minutes before sunrise — and ends at Maghrib (sunset). Suhur is the pre-dawn meal eaten before Fajr; Iftar is the meal that breaks the fast at sunset. Use your local masjid's schedule for exact times.
How many days are in Ramadan?
Ramadan is 29 or 30 days, depending on the moon sighting. Most years it's 30 days, but it can be 29 if the new crescent moon is sighted on the 29th evening. The Islamic month begins and ends with the actual moon sighting in your region.
I missed a fast. What do I do?
For temporary excuses (illness, travel, menstruation, pregnancy/breastfeeding), make up the missed days (qada') after Ramadan and before next Ramadan. For chronic conditions where you cannot fast at all, pay Fidya — feed one needy person per missed day.
What is Fidya?
Fidya is a financial compensation for someone who cannot fast and cannot reasonably make up the fasts (e.g. chronic illness, old age, certain pregnancies). The amount equals one meal's cost for a poor person, per missed day. Most scholars suggest $3–$10 per day depending on local food prices.
What is Kaffara?
Kaffara is a heavier compensation for deliberately breaking a Ramadan fast without a valid excuse (e.g. eating intentionally during fasting hours). The penalty is fasting 60 consecutive days OR feeding 60 needy people. This calculator focuses on Fidya — for Kaffara, please consult a scholar.
Do I have to fast if I'm travelling?
Travellers are exempt from fasting and can make up the days later. The travel exemption traditionally applies to journeys long enough to shorten prayers (around 80 km / 50 miles or more). You can still choose to fast if it's not difficult.
Are my fasts valid if I forget and eat?
Yes — accidentally eating or drinking out of forgetfulness does not break the fast. The fast is valid; just stop as soon as you remember.
When should I pay Fidya?
Fidya can be paid any time during Ramadan, or after Ramadan if you realise you can't make up the missed fasts. Many people pay it in the last 10 nights of Ramadan along with Zakat al-Fitr.
