Ramadan fasting schedule
This works out today's suhoor and iftar times for your location, entirely in your browser — nothing is sent anywhere. It also gives you a simple hydration and energy plan for the day. This is a health tool, not a religious ruling; always follow your local mosque or a trusted timetable for the exact times you observe.
Mosques use different methods. Choose the one your local mosque uses, or check its timetable.
Suhoor ends (Fajr)

Stop eating and drinking by now.

Who does not have to fast
Fasting in Ramadan is for healthy adults. People who are ill, have a condition fasting could make worse, are very frail, pregnant, breastfeeding or menstruating, or are travelling are exempt. If you are unsure, ask your doctor and your imam.
If you have diabetes, see your diabetes team six to eight weeks before Ramadan. Some people with diabetes are advised not to fast. If you do fast, check your blood sugar and break the fast straight away if it is below 3.9 mmol/L (70 mg/dL) or above 16.7 mmol/L (300 mg/dL), or if you have symptoms of a hypo.
Your hydration & energy plan
- At suhoor, favour slow-release carbohydrate (oats, wholegrain), protein and some fat. They keep you fuller for longer than sugary foods.
- Drink steadily between iftar and suhoor, not all at once, so your urine stays pale yellow. Large amounts of tea or coffee can make you pass more water, so keep them moderate.
- Break your fast gently: a couple of dates and water first, then a pause, then your meal. A huge plate straight away often leaves people sluggish and uncomfortable.
- Long summer fasts mean many hours without water, so drink steadily from iftar to suhoor rather than all at once.
- Medication: if you take regular medicine, speak to your doctor or pharmacist about timing it around suhoor and iftar. Never skip essential medication to keep a fast.
City times are shown in that city's local time; "use my location" uses your device's clock. Iftar is sunset; suhoor ends at dawn by the method you choose (the angles are the commonly published values). Times are worked out with a standard simplified sunrise formula, so treat them as a guide: local timetables can differ by a few minutes, and many add a safety margin. In very high latitudes near midsummer, dawn may not occur in the usual way.
How to use the Ramadan times planner
To get Ramadan fasting times, pick your city from the list of 43 or press “Use my location”. Location stays in your browser, and the times then show in your device’s own time zone. If one of the listed cities shares your device’s time zone, the planner opens on that city. Then choose the dawn method your mosque uses.
The planner shows three things for today. These are the time suhoor ends, the time of iftar and the length of the fast. Open “Show the next 30 days” for a table of all three, one row a day, starting today. Ramadan lasts 29 or 30 days, so opening the table on the first day of Ramadan covers the whole month.
How the planner works out Ramadan fasting times
Iftar is sunset. The planner counts sunset as the moment the centre of the sun sits 0.833° below the horizon. That figure adds the sun’s average radius (16 arcminutes) to the usual bending of light at the horizon (34 arcminutes).
Suhoor ends at dawn, when the sun climbs to a set angle below the horizon. That angle is the only thing the dawn method changes. The planner uses a standard simplified sunrise formula, so treat its times as a close guide. Your mosque’s times may sit a few minutes away from the planner’s.
Dawn calculation methods compared
The four methods in the list use the commonly published dawn angles. Here is what each one gives for London on 15 February 2027, worked out with the planner’s own formula.
| Method | Dawn angle | Suhoor ends | Iftar | Fast length |
|---|---|---|---|---|
| Muslim World League | 18° | 5:23 am | 5:14 pm | 11 h 51 min |
| Islamic Society of North America | 15° | 5:42 am | 5:14 pm | 11 h 31 min |
| Egyptian General Authority of Survey | 19.5° | 5:13 am | 5:14 pm | 12 h 0 min |
| Umm al-Qura, Makkah | 18.5° | 5:20 am | 5:14 pm | 11 h 54 min |
A smaller angle means a later dawn and a shorter fast. On this date, the gap between the earliest and latest suhoor is 29 minutes.
Fasting times by location and season
The Islamic calendar moves about 11 days earlier each year, so over the years Ramadan falls in every season. Fast length changes with both the season and how far you are from the equator. These figures use the Muslim World League’s 18° dawn.
| City | 1 Mar 2027 | 1 Jul 2027 |
|---|---|---|
| London | 12 h 43 min | no 18° dawn |
| Chicago | 12 h 46 min | 17 h 21 min |
| Cairo | 12 h 51 min | 15 h 39 min |
| Riyadh | 12 h 54 min | 15 h 8 min |
| Lahore | 12 h 50 min | 15 h 49 min |
| Kuala Lumpur | 13 h 13 min | 13 h 33 min |
| Dar es Salaam | 13 h 24 min | 12 h 59 min |
| Melbourne | 14 h 30 min | 11 h 9 min |
Near midsummer in London, the sun never sinks 18° below the horizon. At 51.5° north on the longest day, its lowest point is about 15° down. On those dates the planner shows a dash instead of a time, and today’s result tells you to follow your local timetable. On 1 July 2027, Glasgow and Edmonton get no dawn time from any of the four methods.
Health, exemptions and diabetes
The planner gives times and health advice only. For religious rulings, ask your imam. The box on this page lists who does not have to fast. If you are unsure whether that includes you, speak to your doctor as well.
If you take regular medicines, keep taking them unless a health professional tells you otherwise. Ask about timing a few weeks before Ramadan, since some doses need changing. Insulin and sulfonylureas lower blood sugar, and a long fast can push it too low. Never change a diabetes medicine yourself.
Many people break the fast with dates and water, a long tradition. Long summer days add to the risk of dehydration. Older people are more at risk, and so are people with heart or lung disease, high blood pressure or diabetes. Stay out of strong sun when you can.
Related tools and guides
For the meal after the dates, the break-fast meal planner suggests a protein-first plate for fasts up to 24 hours. Our page on what you can drink covers water, tea and coffee for the hours between iftar and suhoor. For salt and potassium on long, hot days, read the electrolytes guide.
Frequently asked
What time does the Ramadan fast start and end?
The fast starts at dawn (Fajr), when suhoor ends, and ends at sunset (Maghrib), when iftar begins. The planner works out both times for your city or your location. Dawn depends on the calculation method you choose, and sunset is the same in every method.
Why are the times different from my mosque's timetable?
Mosques use different dawn angles, and many add a safety margin of a few minutes. The planner also uses a simplified sunrise formula, which usually agrees with astronomical tables to a minute or two. Follow your local timetable for the times you keep.
How long is the fast in Ramadan?
It depends on where you live and the time of year. On 1 March 2027 the planner gives about 12 hours 43 minutes in London and 14 hours 30 minutes in Melbourne. On 1 July 2027, Chicago's fast is about 17 hours 21 minutes and Melbourne's about 11 hours 9 minutes.
Is Ramadan fasting the same as intermittent fasting?
Both limit eating to set hours each day. During Ramadan, healthy Muslim adults have no food or drink, including water, from dawn to sunset for 29 or 30 days. Most intermittent fasting plans allow water and black coffee during the fast.
Should people with diabetes fast in Ramadan?
Speak to your diabetes team 6 to 8 weeks before Ramadan. The team will tell you not to fast if your risk is very high or high. While fasting, stop at once with hypo symptoms or a blood sugar outside 3.9 to 16.7 mmol/L (70 to 300 mg/dL).
