Eid is one of the most important events in the Muslim calendar, on a par with Christmas or Yom Kippur for those of other faiths.
On this day, Muslims bid farewell to the fasting month of Ramadan, and also mark the end of the Hajj or pilgrimage - two of the main 'pillars' of the Islamic faith.
Along with mosques around the world, Liverpool's main mosque in Toxteth will be celebrating the occasion, which is the first day of the year for Muslims.
Eid's full name, Eid al-Fitr means "festival of breaking the fast."
The Imaam or chief priest of the Al-Rahma mosque in Hatherley Street, Abu Usamah, said: "Around four to five thousand will come together in the morning to pray.
"The logistics of that is quite daunting so we hold about three different prayer congregations.
"We wish each other a blessed fast and Eid, and then we go and visit each other to eat breakfast for the first time since the end of Ramadan.
"However we also provide food in the mosque for asylum seekers and refugees."
The Imaam added it was important for the younger generation to appreciate the significance of Eid.
Other common features include the wearing of new clothes.
An afternoon funfair will be held in Sefton Park, complete with rides, balloons and clowns, which is open to everyone to attend, including non-Muslims.
