Eid al-Fitr, the "festival of breaking the fast", is the first of the two main festivals in Islam.

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.

Sunni Muslims also regard the killing of Husayn as a tragic event, and Ashura also marks the parting of the Red Sea by Moses and the salvation of the Israelites. Observances differ between communities.
At work: Solemn, so "Happy" does not fit. Be respectful and keep it neutral.
