Muslims around the world are celebrating Eid al-Fitr, to mark the end of the holy month of Ramadan.
It is an important day for Muslims globally, and brings an end to a month-long period of fasting.
Around 5,000 people were expected to gather in celebration at the country's largest mosque in Clonskeagh in Dublin.
"I'm very happy," says 22-year-old Abdullaah Javed, originally from Pakistan.
"Especially in a country like Ireland where today marks diversity and inclusion, where we can practice and follow our religion freely."
For Humeera Butt and her two daughters, the day is about coming together to meet with friends and family.

"This is celebration day," she says. "We offer our Eid prayers and it's like getting together as a community."
This year however, the ongoing violence in Sudan is very much in the minds of those attending the event.
"People are happy here but some of them come from countries where they have conflict," says Dr Ali Selim from the Islamic Cultural Centre.
"I believe their happiness is not full, is not complete because of what's happening in their home countries. We hope peace and security prevail all over the world."
For those originally from Sudan, it is a time of concern.

"It is really affecting us," says Idriss Mohamed. "Stress, stress... I'm very worried. Right now, I can talk to my family by phone, but you never know what will happen in the next hour or two."
Marhim Ibrahim still has family in Sudan. She too is worried about the situation there.
"Every day is terrible. Every day brings more trouble than the day before. We hope the situation will settle."
It is a day of celebration in Clonskeagh, but concerns for those in Sudan remain.

The General Secretary of the Sudanese Community Association in Cork, Dr Osama Ali said Eid is like Christmas for the community, but they will take the opportunity to show solidarity with the international community.
"We would like to see political settlement for this [for Sudan] as this only way out to have a framework establish democracy and war is not the solution for this," he said.
Speaking on RTÉ's Morning Ireland, Dr Ali spoke about his own family in Khartoum facing a very difficult situation but said that some of his family managed to flee to a nearby city in a widow of calm.
