When Does Ramadan Start 2026 – UK Dates, Timetable and Key Facts

Ramadan is the ninth month of the Islamic lunar calendar, observed by Muslims worldwide as a period of fasting, prayer, reflection and community. The start of Ramadan is determined by the sighting of the new crescent moon, which means the exact date can vary slightly between countries and communities. For the UK in 2026, the most commonly expected start date is the evening of Wednesday, 18 February, with the first full day of fasting on Thursday, 19 February.

Because the Islamic calendar is about 11 days shorter than the solar Gregorian calendar, Ramadan moves earlier each year. In 2026 it will fall in late winter, meaning fasting hours in the UK will be around 11 to 12 hours per day – significantly shorter than if it occurred in midsummer. The exact dates remain subject to official moon sighting confirmation, typically announced one or two days before the start.

For anyone asking “when does Ramadan start”, this article brings together the best available UK data for 2026 and 2027, explains how the start date is decided, and provides a practical London timetable to help with planning.

When Does Ramadan Start and End in 2026?

When Does Ramadan Start in the UK in 2026?

UK-facing sources such as UKIM and Barakah.org.uk indicate that the first day of fasting is expected to be 19 February 2026, following the evening moon sighting on 18 February. The Royal Observatory Greenwich is hosting a live new crescent moon watch on Wednesday 18 February 2026, from 5.30 to 6.15 pm, open to the public and online. Some sources also mention the possibility of 17 February if the crescent is confirmed earlier, but the consensus among UK organisations points to 18 February as the most likely start evening.

When Does Ramadan End in 2026?

The end of Ramadan 2026 in the UK is expected to fall on the evening of Friday, 20 March 2026, or possibly Thursday, 19 March, depending on the sighting of the Shawwal crescent. That would make the last fasting day either 19 or 20 March. The transition to Eid al-Fitr is then confirmed by moon sighting authorities.

When Does Ramadan Start in 2027?

For Ramadan 2027, projections from astronomical sources and UK crescent visibility calendars point to a start on Monday, 8 February 2027. The Ahmadiyya UK crescent visibility page gives 8 February as the start, with Eid al-Fitr around 10 March. Moonsighting.com similarly forecasts 8 February 2027 as the beginning of Ramadan 1448 AH. As always, these dates are subject to official moon sighting closer to the time.

How Is the Start of Ramadan Determined?

Moon Sighting Methodology

The Islamic calendar is a lunar calendar, so each month begins when the new crescent moon is first seen after sunset. For Ramadan, this sighting is traditionally done with the naked eye, though many communities now use astronomical calculations to forecast the likely visibility. In the UK, organisations such as Muslim Aid explain that the start date depends on the confirmed sighting of the crescent, which can vary by region and authority.

Why Dates May Vary

Differences in start dates between countries – or even between mosques in the same city – often arise because some groups follow a local sighting while others rely on a global announcement or a calculated calendar. This is why the UK can see a variation of one day. All sources agree, however, that the month will be 29 or 30 days long.

Ramadan 2026 Timetable for London

Daily Fast Duration

Because Ramadan 2026 falls in late winter, fasting hours in London will be relatively moderate. Based on the expected start of 19 February, the first day’s fast will last from dawn until Maghrib (sunset). A London timetable from Barakah.org.uk lists Maghrib (iftar) times of approximately 17:32 on 17 February, 17:33 on 18 February, and 17:34 on 19 February, as the days lengthen slightly through the month.

Key Prayer Times

Each day of Ramadan includes two key prayer times that bookend the fast: Fajr (pre-dawn, when fasting begins) and Maghrib (sunset, when fasting ends). Precise times change daily and vary by location. The UKIM Ramadan timetable provides a full daily schedule for London and other UK cities.

How Certain Are the Ramadan 2026 Dates?

Why Does Ramadan Start on Different Dates Each Year?

Ramadan is the ninth month of the Islamic lunar calendar. Because the lunar year is about 11 days shorter than the solar year, Ramadan begins approximately 10–11 days earlier each Gregorian year. This is why in 2025 Ramadan was in early March, in 2026 it falls in February, and in 2027 it will begin around 8 February.

The length of fasting days also shifts with the seasons. In the UK, February and March days are relatively short, so fasts in 2026 will be around 11–12 hours – much shorter than the 18‑hour fasts that occur when Ramadan falls in midsummer.

Where Do These Ramadan Date Predictions Come From?

“Ramadan is expected to begin on the evening of Tuesday 17th February 2026.”

– Islamic Relief UK

“On 17 February. How long is Ramadan 2026? 29 or 30 days.”

– Muslim Aid

“This year, the Ramadan start date in the UK is expected to be 19 February 2026.”

– UKIM (UK Islamic Mission)

Each of these organisations relies on a combination of astronomical calculation and moon sighting committees. The slight variation in their stated dates (17 vs 19 February) reflects the inherent uncertainty until the crescent is actually sighted.

Key Takeaway for Ramadan 2026

The most widely expected start of Ramadan in the UK for 2026 is the evening of 18 February, with fasting beginning on 19 February and ending around 19–20 March. These dates are subject to official moon sighting, so it is wise to confirm with a local mosque or Islamic centre a day or two before.
