As the title say How should moon to be sighted to celebrate Eid?

I know this is controversial subject because half of Muslim community in the UK did Eid yesterday (Thursday) because they follow Saudi Arabia.

Other half celebrating Eid today (Friday) because they follow Morocco I think. Not sure why though.

Everyone in the UK wish to celebrate same day Eid but the problem is majority of people follow Barelvi‎ and Hanafi.

So what is the solution?

The first thing to do is to have correct our understanding and then base our activities based on it.

Moon sighting is not necessary now

The Prophet Muhammad (PBUH) said a month can be of 29 days. If you see a moon on 29th day, the month ends. If for some reason we can not see the moon, then we should complete 30 days

It was well-established at the time of the prophet (PBUH) that a lunar month can not be more than 30 days. That's why, it was not necessary to see the moon on the 30th day. If seeing the moon was a strict condition, it would have to be seen on the 30th day too.

Now, with the help of science, we can determine the location of the moon at any given location based on astronomical calculations. So we can determine whether the month will have 29 or 30 days.

Make a calendar

Based on astronomical calculation, make a calendar that can be used, not only for religious but also day-to-day activities.

    I understand that but does Quran or Hadith says we should follow our local viewing and if not then the closest Islamic country or follow Saudi Arabia? Aug 13, 2013 at 21:11
  • There are many different astronomical calculation or why is the Um-al-Qurah calendar (which the Saudis follow) often corrected?

I have answered at Local moon or international moon? .

I add here about your example. See these maps: http://moonsighting.com/1434shw.html .

As far as i understand these are visibility that was at sunrise or sunset... to celebrate at august 8 in UK there should be new moon at sunset or sunrise of august 7 seen at proper location on earth.

New moon was firstly visible with optical aid at august 6 21:50 ut at location souther than Australia. What time was there? it is at +10 hours, so, there was 7:50 of morning of august 7.

Also it was later visible with naked eye at southern america's morning of august 7. it is at utc-5, so, it should be 14:50 at uk at that time, if sunrise was also at 7:50, but i see from a map http://www.timeanddate.com/worldclock/sunearth.html?day=7&month=8&year=2015&hour=10&min=50&sec=0&n=&ntxt=&earth=0 that it was nearly 10:50 of august 7 at uk at that time.

So, maybe, it, new moon time, was said about green zone, and it was 18:50 at south america at that time, and i see in stellarium, that new moon is visible at sunset. so, i was wrong, thinking that new moon is not visible at sunset on southern hemisphere.

So, as it was well visible at sunrise of august 7, august 8 can be counted as eid. though, btw, it could be visible badly at sunset of august 7, because moon was not visible at northern areas, and i think that it should not be visible at equator areas, because moon sets almost at same time with sun there, though some mountains could hide sun earlier in some places, and moon sets earlier than sun in southern hemisphere, so it is not visible at sunset there.

As you can see at http://www.timeanddate.com/worldclock/sunearth.html?day=6&month=8&year=2013&hour=21&min=50&sec=0&n=&ntxt=&earth=0 , at evening of august 6 at which new moon was in south america, britain had passed sunset, and it should not be counted for britain, but new moon of august 7 should be counted, and eid at august 8, (i think that if new moon is at sunrise of august 7, it is too late to count august 7 as 1st day of new month).

Is there logic in celebrating Eid at August 9? - If visibility in other place is counted, then it should be celebrated at August 8. If only local visibility is counted, then new moon is visible only with optical aid and only in southern part of UK on August 8, and it is visibility at sunset of August 8. Since it is bad visibility, and only in part of UK, and if criterion is that there must be local visibility in every location, then Eid should be better celebrated at August 10, with that logic.

  • i think, the map at moonsighting.com changed, not i made error...

If I were you, I would follow the majority. So, you have to know the considered by the majority of Muslims around the world. However, if there are a distinguished majority in the UK, so, you have follow them.


The prophet said that if the moon cannot be sighted in your present country, then you should follow the closest Islamic country, which for the UK is Morocco.

  • Even if i would agree with what you say, this doesn't really answer the question!

  • @Bilal from the distance point of view yes, but when it comes to moon sighting morocco at least have about the same latitude (which is not really significant for a local moon-sighting). On the other hand Bosnia doesn't have an independent moon-sighting at just follows turkey AFAIK, while in Morocco each end of a lunar month specialists go and check for the crescent.
