The rest of the calendar: Ashura, Mawlid and the quieter observances.

A calendar kept in many different ways

Beyond Ramadan and the Eids, the Hijri year contains a number of days that families mark, and practice varies enormously: between Sunni and Shia families, between countries, between schools of law, and between one household and the next within the same street. Some of these days are widely observed, some are kept by some communities and not by others, and the questions of which are to be marked and how are matters of religious knowledge on which this office holds no view whatsoever and offers no opinion. What follows is a description of practice as we encounter it, so that arrangements can be made properly.

• Muharram, the first month of the Hijri year, and Ashura on its tenth day
• Arbaeen, forty days after Ashura, observed by Shia families
• Mawlid al-Nabi, in Rabi al-Awwal, marked by many communities and not by others
• Isra and Miraj, in Rajab
• Mid Shaban, the fifteenth night of Shaban
• Laylat al-Qadr, sought within the last ten nights of Ramadan
• Eid al-Ghadir, in Dhul Hijjah, observed by Shia families

Muharram and Ashura

Muharram opens the Hijri year, which in the current part of the cycle falls in early summer, around June, and is moving earlier into May. That places it squarely at the beginning of the Gulf summer travel season, so it is the observance most likely to find a family already in Thailand. For many Sunni families the tenth day is marked by voluntary fasting, which requires nothing more of a hotel than a suhoor and an iftar arranged as they would be in Ramadan, on one or two days rather than thirty.

For Shia families the first ten days are a period of mourning, and the practical requirements are entirely different. A household in mourning observance does not want a celebratory programme, and hotels default to celebration: welcome amenities that arrive with sparkling wine, live music in the lobby lounge below the suite, a birthday cake produced because a date of birth was in the booking system, an invitation to a beach party. None of it is ill intentioned and all of it can be turned off, but only if somebody says so in advance. We put it in the arrival brief as a matter of course: no music in the private areas, no celebratory amenities, no photography, and housekeeping instructed to keep the floor quiet at agreed hours.

Thailand's Muslim community is predominantly Sunni. There is also a long established Shia presence in Bangkok, descended in part from Persian settlers who arrived centuries ago, with its own mosques on the Thonburi side of the river. Access and timings during Muharram are arranged through the community itself rather than through a hotel concierge, and we do not publish addresses or schedules here for that reason. Families who wish to attend majalis are usually best served by asking their own community office at home, which more often than not already knows who to telephone in Bangkok, and we make the arrangements from there.

Mawlid al-Nabi

Mawlid falls in Rabi al-Awwal and currently sits at the end of the Gulf summer, in the second half of August, drifting earlier into August and then July over the coming years. That puts it inside the season when most of our Gulf clients are already in Thailand with their families, which makes it the observance we are asked about most after Ramadan.

Whether and how Mawlid is marked differs between communities and between families, and we take no position on the question. Where it is marked, gatherings are held in Thailand: in the southern provinces they are prominent and public, and Bangkok mosques hold their own programmes, as do mosques in Phuket and Krabi. The practical needs are modest, usually a car in the evening and a mosque that has been telephoned in advance to confirm the timing. Where a family marks the day privately at home, the requirement is a quiet suite, a room that can hold the household, and a kitchen that can produce food for guests at a few hours' notice.

Isra and Miraj, mid Shaban, and the quieter nights

These are kept, where they are kept, largely at home and largely at night, and they place almost no demands on a hotel beyond the ones a hotel should be meeting anyway: a quiet room, a household that is not disturbed, and food available late. What they do require is that nothing be scheduled against them. A family that has told us the date will not be offered a boat trip that evening or a dinner reservation at nine, which sounds obvious until you have seen a concierge cheerfully fill an evening that was meant to be empty.

Laylat al-Qadr, sought in the last ten nights of Ramadan, is the demanding one. Nights run long, some members of the family may be at a mosque until very late or making itikaf for several days, and the household effectively runs on two schedules at once. We staff for it: a second driver on rotation, food available at hours no restaurant keeps, and the rest of the family's programme built so that it does not depend on the people who are praying.

How we ask, without asking

There is a right way and a wrong way for an office to handle this. The wrong way is to ask a family which school it follows, or to guess from a passport, or to make assumptions from a surname. Nobody engages a private office in order to be interviewed about their religion, and a family should never have to explain itself to arrange a car.

The question we ask instead is operational: which dates in this stay must be protected, and what should not be scheduled on them. That single question gets everything needed for the arrangements, in the family's own words, without anyone having to state a position on anything. Some families answer in detail and some answer with two dates and no explanation. Both answers are complete, and the file records what to do rather than why. Our job is to make sure that on the day, the room is quiet, the car is there, the kitchen is ready, and nobody in the hotel does anything thoughtless.

Which observances a family marks, and how, are matters of religious knowledge for your own scholar and your own community: nothing here is a ruling and nothing here is advice. All of these dates depend on the lunar calendar and on local sighting and announcement, so confirm them with your own mosque or Islamic authority at home and, for the Thai dates, with the Office of the Chularatchamontri and the Central Islamic Council of Thailand (halal.or.th). Have any mosque or community gathering confirmed by telephone in advance rather than assumed from an online listing.
