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.
A holiday on the day after the Night of Power (Qadr Night, 27 Ramadan, the revelation of the Qur'an) and on the day after Maouloud, the birthday of the Prophet Muhammad, on 12 Rabi' al-awwal.
At work: Welcome to mention among Muslims. 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.
Easter celebrates the resurrection of Jesus and is the most important feast of the Christian year. Families go to church and share a festive meal, and in many places Easter eggs are decorated and broken together as a symbol of the empty tomb. Easter is a moveable feast, with its date set by a lunisolar calendar. Easter Monday, the day after, is a public holiday in more than 50 predominantly Christian countries.
At work: Widely welcome to mention. Colleagues may be away for the whole long weekend.
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.
Marks 25 May 1963, when representatives of thirty African nations met in Addis Ababa and founded the Organisation of African Unity. When the African Union replaced it in 2002 the date stayed.
At work: Fine to mention. A day off where it is a holiday; the card shows the official days off.
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 Assumption of Mary is the Catholic dogma that Mary, at the end of her earthly life, was taken body and soul into heaven. It is celebrated on 15 August. The Eastern Churches have an equivalent belief, the Dormition.
At work: Fine to mention. A public holiday in many Catholic countries.
A holiday on the day after the Night of Power (Qadr Night, 27 Ramadan, the revelation of the Qur'an) and on the day after Maouloud, the birthday of the Prophet Muhammad, on 12 Rabi' al-awwal.
At work: Welcome to mention among Muslims. A day off.
Marks 2 October 1958, when Guinea became independent from France after a referendum.
At work: Very welcome to mention. 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.
