Earlier this year in May, Muslims around the year celebrated Eid al-Fitr, which marks the end of Ramadan, the holy month for Islam.
Eid al-Adha is the second Eid festival and is considered to be the holier of the two, it begins on July 9.
Here's everything you need to know about Eid al-Adha and Eid al-Fitr, including how to wish someone a happy Eid.

Traditionally, the phrase has been used by Arab Muslims but has spread across both Eids.

What is Eid al-Adha?
Eid al-Adha is the second and the biggest of the two main holidays celebrated in Islam.
Known as the Feast of the Sacrifice, the holy festival commemorates the prophet Ibrahim's willingness to sacrifice his son in order to demonstrate his dedication to Allah.
Eid-al Adha is celebrated on the 10th day of Dhū al-Hijjah, which is the final month of the Islamic calendar.
The religious festival coincides with the completion of Hajj, which is the annual pilgrimage to Mecca that millions of people participate in.
The date of Eid-al Adha changes every year because the Islamic calendar is a lunar calendar, so the dates of annual events vary with the moon's phases.
What is Eid al-Fitr?
Eid al-Fitr is the first of the two main holidays celebrated in Islam. It is a celebration of the end of Ramadan and the period of fasting.
The name translates to ‘festival of the breaking of the fast’, Ramadan sees Muslims fast for either 29 or 30 days, depending on the moons phases, which is used calculate exactly when the holy month ends.
It is also a time to practice self-restraint and while fasting people should also not smoke, swear or engage in sexual relations.

Sweets, dates and confectionaries are typically treats to enjoy during Eid al-Fitr.
Are Eid al-Fitr and Eid al-Adha public holidays?
Neither Eids are an official public holiday in the UK.
This year however, Eid al-Fitr did fall on the early May bank holiday on Monday, May 2.
This meant that Muslims across the UK were able to enjoy a full day off for the holy festival.
And the good news is that Eid al-Adha begins on a Saturday this year, which also means that most Muslim's will be able to enjoy some time off with their family's as they celebrate over the weekend.
