Weekdays by the local weekend (Sunday and Saturday), minus the public holidays most people have off.
The first day of the calendar year in the Gregorian calendar, 1 January. Cultures and religions that follow a lunisolar or lunar calendar celebrate their New Year at other points of the year. Japan celebrates New Year on 1 January, in accordance with the Gregorian calendar, instead of with the Chinese calendar that was in use until 1873.
At work: Fine to mention, and a natural moment to wish colleagues well.
The Isra' and Mi'raj are the Islamic accounts of the Prophet Muhammad's night journey, during which he ascends to the heavens. It is remembered in many Muslim-majority countries, and is a public holiday in some of them.
At work: Fine to mention with respect. A day off in the countries that keep it; the card shows the official days off.
18 March is the death date of Cheikh Al Maarouf, an Islamic preacher.
At work: Welcome to mention with respect. A day off.
Eid al-Fitr, the "festival of breaking the fast", is the first of the two main festivals in Islam. It falls on the first day of Shawwal, the tenth month of the Islamic calendar, and marks the end of the month-long, dawn-to-dusk fasting of Ramadan. It begins with a communal prayer and is followed by visits to relatives, giving gifts and sharing meals.
At work: Very welcome to mention. Its date follows the lunar calendar and shifts every year, so keep plans flexible. During Ramadan itself, colleagues who fast may prefer meetings earlier in the day and not over lunch.
International Workers' Day, on 1 May, honours workers and the labour movement. The date was chosen to commemorate the 1886 general strike in the United States that culminated in the Haymarket affair, and the day was adopted in support of a "great international demonstration" for the eight-hour day.
At work: Fine to mention the day off. In some countries it has a political side, so keep it about the break.
Eid al-Adha, the "festival of the sacrifice", is the second of the two main festivals in Islam. It falls on the 10th of Dhu al-Hijja, the last month of the Islamic calendar. It honours the willingness of Ibrahim (Abraham) to sacrifice his son at God's command. The Eid prayer is held in the morning, followed by the ritual sacrifice of a livestock animal, and celebrations carry on for the three following days.
At work: Very welcome to mention. As with Eid al-Fitr, the date follows the lunar calendar, so keep plans flexible.
The Islamic (Hijri) New Year marks the beginning of a new lunar Hijri year. It is observed by most Muslims on the first day of Muharram, the first month of the Islamic calendar. The Islamic era begins with the Hijrah, the emigration of Muhammad and his followers from Mecca to Medina in 622 CE. It is observed as a public holiday by 24 countries.
At work: Fine to mention. A day off in the countries that observe it.
Marks 6 July 1975, when the Comoros declared independence from France, after a referendum in 1974.
At work: Very welcome to mention. A day off.
Mawlid is an annual festival commemorating the birthday of the Prophet Muhammad, on 12 Rabi' al-awwal, the third month of the Islamic calendar. It was first publicly celebrated by Gökböri, a deputy of Saladin, and the Ottomans declared it an official holiday. Celebrants recite religious poetry in praise of Muhammad.
At work: Respectful to mention. Not every colleague marks it in the same way.
12 November. Since 2005, National Maore Day has been one of the ways of campaigning against the presence of France on Mayotte (Maore); it has been a holiday in the Comoros since 2006.
At work: Be careful: the status of Mayotte is a political issue. A day off.
Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on 25 December. Eastern Christian Churches that follow the older Julian calendar celebrate it on 25 December of that calendar, which currently corresponds to 7 January. It is a public holiday in many countries, and many non-Christians celebrate it culturally too.
At work: Widely welcome to mention. Plan important meetings before the break. If you're unsure whether someone celebrates it, "Happy holidays" is a safe choice.
