Whenever Eid is celebrated on different days by different groups of Muslims, a natural question comes in mind as to why, in this day and age, with all the scientific advancement, we are celebrating Eid on different days!

Eidul Fitr is celebrated on 1st of Shawwal by all the Muslims, but it is determined in the following ways by different Muslim groups:

Option 1: By actual sighting of the new moon with eyes

Option 2: By following Makkah and celebrating Eid on the same day as Makkah

Option 3: By calculation of birth of the new moon, even though it may not be visible to naked eye, even in perfect conditions

Option 4: By calculation of actual sighting of the new moon in perfect conditions

Many Muslim groups in North America use the Option Number 3 where they use the calculation of birth of new moon and do not care whether the moon is actually visible or not in a particular region. Other groups who are orthodox, do not believe in calculation and wait till the last day to try to see the moon with eyes.


Eid-ul-Adha, Hajj or Kaaba point us towards universal brotherhood in Islam. It directs us away from our petty sectarian differences and directs us to the sea that is common between us

A small group follows Eid in Makkah and celebrate on the same day as Makkah. Saudi Arabia has its unique method to determine 1st of Shawwal.

Interestingly, this year depending on the method of determining 1st of Shawwal, Eid could have been celebrated on different days. Here is how:

Based on above options, Eid may be celebrated on following days but not on Aug 8th, 2013:

1. Option 1 – Eid should be on Aug 10

2. Option 2 – Eid should be on Aug 9

3. Option 3 – Eid should be on Aug 7

4. Option 4 – Eid should be on Aug 9

Ahmadiyya Muslim Community follows the Option 4 in which we determine when the moon may be visible if the conditions for viewing are perfect.

As per guidance from our international center in London, we celebrate Eid when the crescent of the moon can be seen. Even if it could only be seen under perfect condition, then Eid may be celebrated the next day. 

Based on the method approved by Markaz, Eidul Fitr was celebrated in North America on Aug 9. Please note the following important facts about this year’s sighting of moon:

While the date for new moon is Aug 6, it was NOT and could not have been visible anywhere in the world until Aug 7.

In North America, the new moon will be visible on Aug 8.

In Canada, the moon could have been visible on Aug 8 only if the conditions were absolutely perfect. It was be easily visible in Canada on Aug 9 as a large thick moon (some people confuse it with 2nd or 3rd day crescent)

As an administrative decision and approved by our international center in London, we celebrate Eid on the same day in North America.

US and Canada communities work together to determine the start of Eids and Ramadan and mutually decide after reviewing sightability of moon in various cities of North America covering from east coast to west coast. These dates are further verified from authentic observatories and only then announced in the Calendar of Events of both countries.

This means that if the moon is visible anywhere in North America, then Eid is celebrated the next day both in USA and Canada.

This year, In Ecuador and Chile, the new moon could have been visible under perfect conditions on Aug 7th, therefore in that region, Eid could be celebrated on Aug  8. However, it will be easily visible only on or after Aug 8 in Ecuador.

The visibility of the crescent is dependent on the following conditions:

– The conjunction (birth of new moon) has occurred before sunset (Minimum age 17 hours)

– The crescent or the moon sets after sunset where there is possibility of visibility.

– The angle between the crescent and the horizon at sunset is at least 5 degrees (preferably 10 degrees)

– The distance between the sun and the moon is at least 8 degrees

A simpler general criteria for sighting of moon, that was recommended by our international center in London, is that for a given country or region:

– if the age of the moon is 20 hours,
– the moonset is after 40 min of sunset and
– the angulation is 10 degrees,

then it is considered that the new moon would be visible. For most parts of the world, even if 2 out of the 3 criteria is met, then it is acceptable.

However, it should be noted that astronomical calculations are accurate for the position of moon, but astronomers differ on calculations for sighting based on many factors. In Astronomy, a new moon means “when the moon of the previous month disappears (i.e. the moon goes from a slightly visible crescent to a completely black sphere that is impossible to be seen).” Remember, new moon is dark and invisible. About 17-23 hours after the new moon, a thin crescent becomes visible on earth; this is visible new moon.

As we are taught by Allah (Qur’an 2:190) and the Prophet Muhammad (peace be upon him), it is the sighting of this crescent that marks the start of a new month. Therefore, even though a moon may be born on one day, it may not be seen until the next day.

Furthermore, if a new moon is born less than 15 hours before sunset on day 1; it will not be seen until sunset of day 2; and when it is finally seen it is 15+24=39 hours old and will look very thick. This does NOT mean that this is a second day or third day moon.

A first day crescent-moon can be very thin in some locations and it can also be very thick in other locations because of the time difference.

Hazrat Abul Bakhtari reported:

We went out to perform Umrah and when we encamped in the valley of Nakhlah, we tried to see the new moon. Some of the people said: It was three nights old, and others (said) that it was two nights old. We then met Ibn Abbas and told him we had seen the new moon, but that some of the people said it was three nights old and others that it was two nights old. He asked on which night we had seen it; and when we told him we had seen it on such and such night, he said the Prophet of Allah (peace be upon him) had said:

Verily Allah deferred it till the time it is seen, so it is to be reckoned from the night you saw it. [Sahih Muslim]

This year the new moon occurred on August 6th. Due to the timing of the new moon, it was extremely unlikely that a sighting of the new crescent moon would be made on August 6th.

An optically-aided sighting of the new crescent moon may have been possible from South Africa on August 7th.

Under excellent conditions, it was possible that a sighting of the new crescent moon could be made from the northern half of South America on August 7th. However, an easier sighting may also be possible from the southern half of South America and parts of Polynesia on the same day.

Easier sightings of the new crescent moon was possible on August 8th from Australasia, south-east Asia, India, the Arabian Peninsula, Africa and the Americas except Canada.

The rest of the world including Asia, Europe and the British Isles and Canada had to wait until August 9th to make their sightings. Hence UK celebrated Eid on Saturday!

Based on the above facts, it was impossible to see the new moon in Canada or USA before August 8. Therefore, Eid was on Aug 9th. In fact, if we only consider Toronto or Canada, then Eid could have been celebrated on Aug 10th (instead of Aug 9 which was valid for North America as we have decided to celebrate Eid together in USA and Canada).

Based on any scientific method of calculation and in the opinion of all the observatories, the sighting of new moon is not possible in North America before Aug 8th. Unless some one wants to use the sighting of moon in South America, it would not be right to celebrate Eid on Aug 8 based on the above 4 methods.

One may debate which option, out of the 4, we should follow or why we do not take the birth of the new moon instead of sighting of the new moon for calculation. These are good discussion items but are more of administrative decisions and by the grace of Allah we have the guidance of Khulafa that has guided has to follow sighting of new moon.

On the lighter side, non-Ahmadis made the mistake on start of Ramadhan, which they cannot fix now and they cannot have Ramadhan of 31 days so now they are caught in the trap and have no choice but to make the wrong decision. Also, some Non-Ahmadi Muslims do not like Eid on Friday because they consider it a bad omen!

For us, this year, it was Eidain as we celebrated it on a Friday.
I hope the above is helpful. For further information on this topic or if you have any questions, please feel free to email or call.

Kaaba.  The Muslim Times’ Chief Editor’s comment: I believe that all of us look at the watch and don’t call the local or regional Imam to find out, if it is time for Salat or not. Likewise, if most of the enlightened Muslims start calling the national observatory for the Eid day, the others with a fundamentalist strain or other agenda will simply gradually follow over time.

  1. I feel this is one subject which is given unnecessary importance.

    Rasoolullah (sas) asked his followers to sight the new moon to ensure the month of Ramadhan has elapsed. This was because there was no other method of calcuation of months available at that point in time.

    Science has progressed so much now that it is possible to calculate the lunar months with precision to the second. It therefore is only whimsical that muslims are still falling prey to the mullahs who want to continue dominating the decisons of celebtrations in the Umma.

    The world has progressed on all other matters of faith. In Islam, Salat hold precedence in the life of a muslim over fasting in Ramadhan, and this is something that is practiced every day. The timings of the Salat was also dictated on the bases of the waning of the sun; however no one nowadays looks at the sun to decide on the prayer timings.

    It is time we woke up, and walked ahead.

  2. science can predict storms and other natural events ahead of time, similarly astronomy can predict new moon ahead of time. But who can convince the central authority in the Islamic world to start using astronomy. Unfortunately there is no central religious authority that can do so. Hence the quarrels over the sighting of the new moon and two eids will go on into the next millennium. Guardian of the Two Houses cannot do this either.

    Alhamdulillah, ALLAHU Akbar! In your comments You each have the explanation for celebrating ‘Eid according to your time zone. True that the sun is not watched for Salaah times these days, but still your local calculations for Salaah times are based on the waning of the sun in your country or state or province etc. – I think this is also why we don’t have Sehri and break Fast with the Saudis,even though the times for Arabians to begin and break fasts are probably scientifically established these days. The people in a particular country will not pray Tahajjud at the time an Arabian would pray…although we are here in SA or which ever country you’re in. So it makes sense that the days of ‘Eid are a few hours apart in different regions of the world. – Subhanallah, ALLAH Knows Best. Jazakallah.

    • Alhamd-u-Lillah.,, hi this matter is easy and clean as Irfaan says.
      Takwa and prayership is the essential spirit, Allah already knows what’s in the kuluub.
      Also, this difference of did timing is not a bad thing, however a virtue. Every single Muslim is easy to understand and pray his eid in his country.

      It’s more and most important, not to deny any muslim’s correct ichtihad (true desicion according to Sunnah -SAV-). So, tavheed-i kuluub is far precious than eid on the same day.

      I tried to express my best wishes.

      you all brothers and Irfaan.

      Muhammed Said

  4. Alhamdulillah. Some people will debate upto th egrave. No mattar what hey say. Allah knows best. I do also agree with Mr. Irfaan.

  5. in my opinion the rohiat-e-Hilal committee in Pakistan has no more job to do to

    announce the moon sighting any more because the present IT technology.

    the Mullan monopoly must be banned.

  6. We are ordered to fast and break fast by seeing the new moon. If on the 29th Shaaban the moon is not visible,we complete Shaabanwith 30 days and fast on the next day whether the moon is sighted or not?
    For Eid all fitr it is the same procedure
    We look for it in our neighborhood,country, then closest country and then Saudi
    We are asked to fast by sighting or the news of sighting by a reliable person
    It is very easy but we are complicating it

  7. I believe that all of us look at the watch and don’t call the local or regional Imam to find out, if it is time for Salat or not. Likewise, if most of the enlightened Muslims start calling the national observatory for the Eid day, the others with a fundamentalist strain or other agenda will simply gradually follow over time.

  8. Thanks for giving great information but it’s a small request. What a nice if you write on the Same topic with collecting all Aayats of Quaran and Hadith and than explain your experience and research.
