The worldwide moon sighting reports by members of the Islamic Crescents Observation Project (ICOP) since 1998 showed that Muslims across the world were fasting Ramadan and celebrating Eid over 4 to 5 days, instead of 1 or 2 days. It has been proven from reliable sources (e.g. Kordi, 2003) that the main cause of the Ramadan and Eid divisions across the whole world, such as in the UK/Europe and North America, were caused by the false moon sighting reports from Saudi Arabia as a result of their civil (Ummul Qura) calendar starting the months before the birth of the moon (New Moon Conjunction) or when the moon has set before the sun.

The above errors of Saudi Arabia were well-recognised by the Muslims of the UK at least a decade before the inception of ICOP and hence an International Moon Sighting Conference was held in London Central Mosque and the Islamic Cultural Centre (Regent’s Park Mosque) in 1984. This conference was attended by over 350 scholars from many Muslim countries around the world. The UK scholars included people from different schools of thoughts/maslak (e.g. Deobandi, Baralwi, Salafi etc) as well as the representative of Jamiat-e-Ulama Britain. They all unanimously agreed to naked eye moon sighting reports, which included the condition that any reports from abroad will only be accepted if the moon was on the UK horizon (i.e. moonset after sunset).

The agreed 1984 criteria closely matched moon sighting reports from the nearby countries to the UK, including Morocco. Unfortunately, members of Jamiat-e-Ulama and Hizbul Ulama found it difficult to follow the 1984 criteria in the following year and decided to abandon it by holding a meeting at Darul Uloom Bury in 1986, to follow Saudi Arabia instead (see UK Moon Sighting History). This meeting resolution was signed by all their delegates (i.e. 11 signatures from Jamiat-e-Ulama and 10 signatures from Hizbul-Ulama) as shown below.

All agreed decision of New Moon

All the Muslims of Britain will have the pleasure of hearing this that the Jamiat Ulama Britain and the Hizbul Ulama UK’s delegates held a meeting on 28th of December 1986 after Magrib prayer at Darul-Uloom Bury under the sadarat [chair] of Maulana Yusuf Motala Sahib and naib sadarat [vice chair] of Maulana Musa Karmadi Sahib about the New Moon in Britain. In this meeting both Jamats agreed after a lot of discussion under the Islamic Law that the New Moon in Britain will be based on “Saudis” New Moon. And then be decided about the dates of Ramadan, Eids and the Islamic Months. This agreement was passed by the undersigned delegates:

Representatives of Central Moon Sighting Committee (Jamiat Ulama Britain and Hizbul Ulama UK)

This resolution was widely publicised in their Mosque Noticeboards throughout the UK and the vast majority of the Muslim population were misguided by them to follow Saudi Arabia. They continue to do so over past 30 years, even with numerous independent evidences of false moon sighting reports from Saudi Arabia.

The recent publication in The Observatory Journal (Alrefay et al, 2018) with 27 years of moon sighting reports from Saudi Arabia by highly experienced astronomers also prove the past errors of announcements made by the Saudi Supreme Court. Therefore, the resolution of 1986 Darul Uloom Bury meeting to follow Saudi Arabia is proven to be false/invalid, due to the widespread misunderstanding of these technical matters. We urge all right-minded Muslims to avoid following news from distant countries (such as Saudi Arabia), and adopt local (or regional) moon sighting instead, as reported to our ICOUK.net website (see Moon -> Observation Results).

You are advised to visit the location during daylight hours prior to the actual date of observation to note the sunset position and any other safety issues.

Some locations may not be suitable for children or elderly (or other vulnerable adults), especially during the darkness after sunset. Group travel is always advisable (to include at least two adults) for your own safety and for verification of the observation report.

Are you making a Gregorian calendar with Hijri dates?

If yes, that’s great MashaAllah, as Allah orders in the Quran (2:189/9:36) to establish the Hijri Calendar based on verified moon sighting by the human eye (Muhaqaq Ruyat Basari)!

What is Imkan Al-Ruyat or Predicted Crescent Visibility?

The Imkan Al-Ruyat or Predicted Crescent Visibility is based on the following 3 conditions:

  1. the New Moon Conjunction (or the Birth of the Moon) must occur before local sunset,
  2. the moonset must be after sunset, i.e. the moon must be above horizon at sunset and
  3. the width of the crescent moon must be large enough to be detected by the human eye (after sunset).
Is your calendar based on Birth or Visibility of the Moon?

Many people who use the old estimates of Hijri dates based on (1) the New Moon Conjunction or (2) the Moonset after sunset, will be 1 or 2 days ahead of the actual visibility of the moon. To use the old estimates (or calculations) and simply state “Subject to Moon Sighting”, is very misleading as that sets false/incorrect expectations of the Ramadan and Eid dates!

The Hijri calendar is LOCAL and not GLOBAL by definition

The Hijri Calendar starts at local sunset from the Sunnah of Prophet Muhammad (ﷺ) and since the world is a globe (with Time-Zone differences), it is a LOCAL and not a GLOBAL calendar. It is against the Sunnah to follow moon sighting news form distant countries (see Kuraib Hadith). Therefore, the UK Muslims must adopt local moon sighting all year round, including Ramadan and Eid, and not follow distant countries (e.g. Saudi Arabia or South Africa)!

Examples of the Gregorian calendar with Hijri Dates

The principle of Local Moon Sighting is the original position from the Quran and Sunnah. However, due to the adverse weather conditions in the British Isles, the UK Muslims have been advised in the past to follow Morocco for reliable moon sighting news (see Fatwa section), as an interim solution.

Therefore, the examples of the Gregorian calendar with Hijri Dates for January 2021, 2022 and 2023 given below are based on the predicted crescent visibility (Imkan Al-Ruyat) for the UK to Morocco Region, whilst working towards a community consensus on a UK-only solution, InshaAllah.

GregHiri2021 1442 GregHiri2022 1443 GregHiri2023 1444

Note that the start of the week is from Sunday (Yawm Al-Ahad/يوم ٱلْأَحَد, the First day) and not from Friday or Saturday, which is mentioned in the Commentry of the Quran (see Tafsir Ibn Kathir, Quran 7:54).

(Adapted from a newspaper report, “When is Eidul-Fitr 2021?” by Eng. Qamar Uddin; dated 20 April 2021)


There is a difference of opinions between Muslim scholars if the lunar month should start with the BIRTH of the moon or the VISIBILITY of the moon. Those who follow the BIRTH of the moon (eg. Saudi Arabia) generally will start the lunar month one day (24 hrs) ahead of those who follow the VISIBILITY of the moon (eg. Morocco). This will be the case in almost every month of the year (or at least in 11 out of 12 months).

There is yet another established difference of opinions between the Muslim scholars about Local Sighting (Ikhtilaf Matale) or Global Sighting (Ittihad Matale) criteria. In the earlier centuries (i.e during the pre-telecommunications era) when Muslims were confined to a small area of the Globe, what was considered as Global Sighting then, can now be re-defined as Regional Sighting (eg. the UK to Morocco region), which has been practised by many of the UK Muslims due to the adverse UK weather conditions in the past.

A few of our ICOUK members have asked about the possibility of switching to UK-only Local Moon Sighting criteria, for a United Eid by all groups, so you may wish to consider the following data analysis/proposal.

Possibility of Local Moon Sighting Criteria

The reason we started 2-days moon sightings since 2018, with the “Spot the Moon Photo Competition” was to encourage the UK Muslims to look for the moon when it was scientifically possible to be sighted in the UK (and not just look for it on the 29th date of a foreign country!). Furthermore, one of the main reasons for doing so was to evaluate this very possibility of adopting a Local Moon sighting (or UK-only) criteria. [Ref: Why look for the moon after 29th date?]

The observation data collected over the past 4-years (2018 – 2021), shows that indeed, it is both scientifically and practically possible to sight the first day’s crescent moon on the UK horizon (provided enough people are looking for it) and it also meets the Shariah requirement of 29/30 days long months throughout the whole year. [Ref: View Observation Results]

However, we have consistently faced the difficulties of not having enough people looking for the moon in the winter months (Nov – Feb) or enough area coverage when most people are still at work (during sunset times around 4 PM). This lack of support during the winter months will make the change to a UK-only criteria very unreliable (until we have wider community support) and has the potential for further divisions/disunity.

Proposal for Local Moon Sighting Criteria

The adverse UK weather conditions and the lack of sighters have forced the UK Muslims to borrow moon sighting news from nearby countries with similarities of moonrise times. Indeed, the vast majority of the UK Muslims did agree to follow Morocco for the past 50-years (since 1970’s), based on the well-established Regional Moon criteria for centuries! [Ref: Why Two Eids? By Allamah Khalid Mahmood (RA)]

However, there was an unfortunate event in the 1980’s that led some of the UK Muslims to follow Saudi Arabia which resulted in divided Ramadan/Eid ever since! [Ref: History of UK Moon Sighting]. Nevertheless, if both these groups were willing to leave foreign countries altogether and unite on UK moon sighting (ie the British Isles), then that will be a very commendable achievement, InshaAllah.

Up to now, we have undertaken the role of the public to do Sighting and Reporting (see the ICOUK website). However, when we adopt an independent Local Moon Sighting System, we will need to undertake Testimonies and make Declarations too, very rapidly and accurately (within 1-hour of UK sunset times).

To facilitate a rapid and accurate testimony procedure (acceptable in Hanafi Fiqh), we will need two types of people with specialist skills working as a team in each of the UK Regions. These people must include a few Ulama to take Testimonies (Shahada) and a few IT Admins to facilitate face-to-face and/or remote audio/video links that work flawlessly! [Ref: Hilal Testimony Procedure]

Finally, we will need to provide the necessary training to the above types of people for a few months, followed by a few months of practice with real witnesses before going live from a future date (with a common starting point, e.g. March 2022/Shaban 1443) that is well-publicised for a further few months by all-party Ulama and Community Leaders.

Proposed Time-Scale
  • May – July 2021 (Shawwal – Dhul Hijjah 1442): Formation of UK Regional Testimony Groups (x 12)
  • Aug – Oct 2021 (Muharram – Rabi-I 1443): Training of UK Regional Testimony Groups
  • Nov – Feb 2022 (Rabi-II – Rajab 1443): Practice/ Publicity of UK Regional Testimony Procedure
  • Mar 2022 (Shaban 1443): Switch to Local Moon Sighting on a common date for UK, Morocco, Saudi UQC
