Frequently Asked Questions

What is today's Islamic date in the UK?

The Islamic date in the UK is calculated using the lunar calendar of 354 or 355 days. The date on this page is based on the widely-used Umm al-Qura calculation; final dates for major events are confirmed by UK moon sighting bodies and may differ by one day.

When is Ramadan 2026 in the UK?

Ramadan 1447 AH is expected to begin around Tuesday 17 February 2026 in the UK, subject to moon sighting. The first day of fasting begins the day after the new moon of Ramadan is confirmed.

When does the Islamic day begin?

The Islamic day begins at sunset (Maghrib), not midnight. In the evening, the Hijri date is the date of the following Gregorian day. This matters particularly in UK summer when Maghrib can fall after 9pm.

Why do some Islamic dates differ by one day?

Different methods exist for determining when a Hijri month begins: astronomical calculation, local moon sighting, or following Saudi sighting. In the UK, dates may differ by one day from those in Muslim-majority countries depending on which method is followed.
