festival spirit

Why do Muslims around the world not agree on which day Eid is?

Physically sighting the new moon and a bit of earthly politics means deciding when Ramzan ends is always a cliff-hanger.

Every Ramzan is a nail-biting finish for fasting Muslims. As the month draws to a close, the exact date for Eid-ul-Fitr festival, which ends Ramzan, depends on the sighting of the new moon.

For theological matters, Islam follows a lunar calendar. The lunar year, however, adds up to about 354 days. Thus Islamic months are out of step with the solar year and the date of Eid falls back by about 11 days every solar or Gregorian year. As a result, throughout history, while Muslim administrations have conducted religion using the Islamic calendar, other more prosaic matters such as tax collection were usually conducted using solar calendars.

Sticking to tradition

But there’s more confusion still. Traditionally, a lunar Islamic month (29/30 days) starts with the new moon. Here’s what that the months means in lunar terms:

Now, given the state of modern-day astronomy, the date of a new moon can be predicted with pin-point accuracy. However, most Muslims chose not to exercise this new-fangled option. Canonically, the Islamic month always began when the first crescent was spotted in the sky. When Islam started out in the sixth century, this was probably the only way the new moon could be approximated. However, the emphasis on the new moon in the Islamic calendar actually spurred Muslim scholars to study astronomy. One sect, the Ismailis (of which Bohras are a subsect) accepted the use of astronomy. However, most other Muslim sects rejected it in favour of visual sighting.


Clambering on to rooftops to peer at the sky at the end of Ramzan might be exciting but it results in a fair bit of confusion given the sheer size and geographical spread of the global Muslim community. Saudi Arabia, for example, often celebrates Eid a day ahead of India. However, in India, Kerala often follows not Delhi but Saudi Arabia, synchronising its Eid with Mecca. In Indonesia, the Muhammadiyah and the Nahdlatul Ulama, the country’s largest Muslim groups, often fail to agree on one date for Eid. In Lucknow, Eid dates are sometimes split according to Shia and Sunni with some clerics being able to spot the moon and others being bested by a cloudy sky.

India’s Muslim-majority neighbours, Pakistan and Bangladesh have national moon sighting committees. This makes for less confusion. However, in Pakistan even this centralised approach has regularly been embroiled in controversy. As it so happens, much of this opposition has run along political lines. In 1967, as Pakistan’s largely secular army dictator Ayub Khan, clashed with the Islamic right, matters took a lunar turn. The Jama’at-e-Islami, a far right party, and many other clerics refused to follow a scientifically determined one-nation-one-Eid formula. For his intransigence, Khan had the head of the Jama’at (as it so happenes, a Partition migrant from Aurangabad in current-day Maharashtra) jailed for almost two years. In today’s Pakistan, the province of Khyber-Pakhtunwa regularly disagrees with the Central government’s Eid date.

Minority dissidents

In this, a few bodies and clerics do support using astronomical calculations. One is the Fiqh Council of North America that contends that using using “scientifically authenticated astronomical calculations are a valid Islamic source of confirming or negating an Islamic month”. In India, Lucknow cleric Kalbe Sadiq also supports the use of astronomy to fix dates.

However, both Sadiq and the Fiqh Council of North America are in a minority and most of the word’s Muslims still prefer to stick with eyewitness accounts of the moon’s status before opting to celebrate Eid.

Following a mountaineer as he reaches the summit of Mount Everest

Accounts from Vikas Dimri’s second attempt reveal the immense fortitude and strength needed to summit the Everest.

Vikas Dimri made a huge attempt last year to climb the Mount Everest. Fate had other plans. Thwarted by unfavourable weather at the last minute, he came so close and yet not close enough to say he was at the top. But that did not deter him. Vikas is back on the Everest trail now, and this time he’s sharing his experiences at every leg of the journey.

The Everest journey began from the Lukla airport, known for its dicey landing conditions. It reminded him of the failed expedition, but he still moved on to Namche Bazaar - the staging point for Everest expeditions - with a positive mind. Vikas let the wisdom of the mountains guide him as he battled doubt and memories of the previous expedition. In his words, the Everest taught him that, “To conquer our personal Everest, we need to drop all our unnecessary baggage, be it physical or mental or even emotional”.

Vikas used a ‘descent for ascent’ approach to acclimatise. In this approach, mountaineers gain altitude during the day, but descend to catch some sleep. Acclimatising to such high altitudes is crucial as the lack of adequate oxygen can cause dizziness, nausea, headache and even muscle death. As Vikas prepared to scale the riskiest part of the climb - the unstable and continuously melting Khumbhu ice fall - he pondered over his journey so far.

His brother’s diagnosis of a heart condition in his youth was a wakeup call for the rather sedentary Vikas, and that is when he started focusing on his health more. For the first time in his life, he began to appreciate the power of nutrition and experimented with different diets and supplements for their health benefits. His quest for better health also motivated him to take up hiking, marathon running, squash and, eventually, a summit of the Everest.

Back in the Himalayas, after a string of sleepless nights, Vikas and his team ascended to Camp 2 (6,500m) as planned, and then descended to Base Camp for the basic luxuries - hot shower, hot lunch and essential supplements. Back up at Camp 2, the weather played spoiler again as a jet stream - a fast-flowing, narrow air current - moved right over the mountain. Wisdom from the mountains helped Vikas maintain perspective as they were required to descend 15km to Pheriche Valley. He accepted that “strength lies not merely in chasing the big dream, but also in...accepting that things could go wrong.”

At Camp 4 (8,000m), famously known as the death zone, Vikas caught a clear glimpse of the summit – his dream standing rather tall in front of him.

It was the 18th of May 2018 and Vikas finally reached the top. The top of his Everest…the top of Mount Everest!

Watch the video below to see actual moments from Vikas’ climb.


Vikas credits his strength to dedication, exercise and a healthy diet. He credits dietary supplements for helping him sustain himself in the inhuman conditions on Mount Everest. On heights like these where the oxygen supply drops to 1/3rd the levels on the ground, the body requires 3 times the regular blood volume to pump the requisite amount of oxygen. He, thus, doesn’t embark on an expedition without double checking his supplements and uses Livogen as an aid to maintain adequate amounts of iron in his blood.
