You break your fast in Ramadan at Maghrib, the moment the entire disk of the sun disappears below the horizon. This is sunset, and it marks the start of Iftar. The exact minute changes every day and varies by location, so most people follow a local prayer timetable or a mobile app that calculates Maghrib for their coordinates.
How Sunset Is Determined
The Islamic definition of Maghrib aligns with the astronomical definition of sunset: the point when the upper edge of the sun, called the upper limb, drops completely below the horizon. You don’t need to wait for the sky to darken or for the redness to fade. As soon as the full disk is gone from view relative to your specific location, the fast is over.
Prayer time apps and printed timetables calculate this moment using your geographic coordinates, elevation, and the date. Different Islamic organizations use slightly different twilight angles for Fajr and Isha prayers, but Maghrib itself is consistent across nearly all calculation methods: it’s simply when the sun sets. Whether your local mosque follows the Muslim World League, the Islamic Society of North America, or the Egyptian General Authority of Survey, the Maghrib time will be the same or differ by only a minute.
When the Fast Begins Each Morning
The fasting window opens at Fajr, the moment of “true dawn” when the first light appears on the horizon. Most timetables also list a time called Imsak, which is a precautionary buffer set about 10 to 15 minutes before Fajr. The purpose of Imsak is to give you a margin so you can finish your pre-dawn meal (Suhoor) and be confident you haven’t eaten past the actual start of Fajr. You’re not strictly required to stop at Imsak, but it’s a safeguard many people rely on, especially when eating close to the cutoff.
What to Eat and Drink First
The prophetic tradition is to break the fast with dates. Fresh dates are preferred, then dry dates, then water if no dates are available. This isn’t just ritual. After a full day without food or water, your blood sugar is low. Dates contain a mix of glucose, fructose, and sucrose that raises blood sugar quickly without the crash you’d get from processed sweets. They’re also high in potassium, which helps your body retain the water you drink alongside them. Starting with a few dates and a glass of water is the most efficient way to address both energy and dehydration at once.
Drink your water before you start eating solid food rather than during the meal. Water consumed alongside food can slow digestion, which matters more than usual when your stomach has been empty all day.
How to Structure Your Iftar Meal
After dates and water, many people pray Maghrib before sitting down for the main meal. This built-in pause of 10 to 15 minutes gives your body a chance to register the initial sugar and fluid, which helps prevent overeating.
When you do eat your main meal, sequence matters. Start with a good source of protein (chicken, meat, eggs, paneer) along with healthy fats like nuts, avocado, or ghee. Follow that with fiber and carbohydrates from rice, bread, or vegetables. This order slows the absorption of carbohydrates and helps prevent the blood sugar spike and crash that leaves you feeling sluggish after Iftar.
Dates are alkaline, which helps neutralize the stomach acid that builds up during a day of fasting. Jumping straight into heavy, fried, or very rich food can overwhelm your digestive system. The first two or three days of Ramadan are the hardest for portion control because your body hasn’t adjusted to the new eating cycle. After that initial period, eating in moderation becomes easier.
Adjusting Medications Around Fasting Hours
If you take daily medication, the fasting window compresses your dosing schedule into the hours between Iftar (sunset) and Suhoor (pre-dawn). For medications you normally take once a day, you can often simply shift the dose to one of those two meals. For medications taken multiple times a day, switching to a long-acting or sustained-release version can reduce the number of doses you need. Short-term medications like antibiotics or pain relievers can sometimes be replaced with once-daily alternatives that fit within the eating window. Talk to your pharmacist or doctor before Ramadan starts to work out a schedule that keeps your treatment effective without breaking the fast.
Checking Your Local Time
Because Maghrib shifts by a minute or two each day as the days grow longer or shorter, you’ll want a reliable daily source for your exact location. Mosque-published timetables cover the entire month at once. Apps like Muslim Pro, Athan, or Al-Moazzin calculate prayer times using GPS and let you choose which calculation authority to follow. If your community uses a particular method, match your app to that standard so your Iftar time aligns with the local adhan.
In northern latitudes during summer months, sunset can be extremely late, pushing fasting hours to 18 or even 20 hours. Some scholars permit following the timetable of the nearest city with a more moderate fasting window, or the timetable of Mecca, in cases where the local schedule creates genuine hardship. If you’re in this situation, consult your local imam for the ruling your community follows.
