Ramadan is the ninth month of the Islamic lunar calendar, during which Muslims fast from dawn until sunset as an act of worship and self-purification. Understanding the precise timing and conditions of the fast helps worshippers organize their spiritual, social, and daily routines around this blessed month.
The dates of fasting shift each year on the Gregorian calendar, and slight variations can appear between communities due to differences in moon sighting methods. The following sections outline when Muslims fast during Ramadan, how local conditions affect the schedule, and practical guidance for performing the fast correctly.
| Month | Islamic Calendar | First Possible Gregorian Date | Last Possible Gregorian Date |
|---|---|---|---|
| Ramadan | 9th month | 10 April | 11 May |
| Fasting begins each day | At dawn (Fajr) | Approximately 1 hour before sunrise | Varies by location and season |
| Fasting ends each day | At sunset (Maghrib) | Depends on latitude and time of year | Earlier or later by latitude |
| Night prayer (Tarawih) | After Isha | Typical start: 1–2 hours after sunset | |
Determining the Start and End of Ramadan
The beginning and end of Ramadan are established by the sighting of the waxing crescent moon, following the teachings of the Prophet Muhammad. Communities may rely on local moon sightings, astronomical calculations, or regional announcements from authoritative religious bodies.
Because the Islamic lunar year is about 354 days, Ramadan moves roughly 11 days earlier on the Gregorian calendar each year. In tropical regions, the fast can exceed 18 hours, while in higher latitudes, adjustments or exemptions may apply to prevent extreme hardship.
Moon Sighting Methods Around the World
Different countries and Islamic organizations follow varying moon sighting protocols, which can lead to differences in the exact start date of fasting. Some prefer physical observation, while others accept credible astronomical calculations or rely on decisions from religious authorities in Saudi Arabia or elsewhere.
Muslims living in diaspora communities often follow the ruling of their local mosque or the broader consensus of their country of residence, while others may choose to adhere to the sighting in Mecca. Understanding these practices clarifies when communities begin and end the fast on the same day.
Geographic and Seasonal Impact on Fasting Hours
The latitude and time of year dramatically influence how long each day of fasting lasts. In summer months, high-latitude regions experience very long days, while in winter the fasting window becomes much shorter.
Islamic scholars have issued guidance for regions where the night does not fall below twilight for an extended period, allowing alternative methods such as following Mecca time, calculating based on the nearest Muslim-majority country, or adopting a standard 12-hour day and night split to avoid severe difficulty.
Practical Guidance for Daily Fasting
During Ramadan, fasting begins at Suhoor, the pre-dawn meal, and continues until Iftar, the meal at sunset. Muslims abstain from food, drink, and marital relations during daylight hours, while also refraining from negative behaviors and focusing on prayer, charity, and self-discipline.
Those who are ill, traveling, pregnant, breastfeeding, or experiencing menstrual cycles are temporarily exempt and must make up the missed days later. Elderly individuals and people with chronic health conditions are encouraged to consult medical and religious professionals to determine a safe approach to fasting.

FAQ
Reader questions
Do I have to fast on the same day as my local mosque if the moon was not sighted in my city?
Many scholars advise following the majority community or the reliable Islamic authority you trust, even if local sightings differ, to preserve unity and avoid confusion in worship schedules.
What should I do if I live in a country above the Arctic Circle where the sun does not set for weeks in summer? Follow the ruling of your local Muslim council or adopt a moderate schedule, such as fasting according to Mecca time or splitting day and night into equal 12-hour periods to avoid extreme hardship. Can I fast on days outside of Ramadan, and does it carry the same reward?
Voluntary fasting on days like the six days of Shawwal, Mondays and Thursdays, or the Day of Ashura can bring additional rewards, but only the month of Ramadan is obligatory and carries the unique multiplied rewards prescribed by God.
What if I accidentally eat or drink while fasting, and does my fast break immediately?
If the mistake is unintentional and you stop as soon as you realize, your fast remains valid; if it is deliberate, you must make it up later. Consult a knowledgeable scholar if you are unsure about the validity of specific situations.
