The federal government has declared Friday, June 15, and Monday, June 18, as public holidays to allow Muslims in Nigeria join their counterparts across the world to celebrate the 2018 Eid- El Fitr, Abdulrahman Dambazau, a minister, has announced.
Should a crescent moon be spotted on tonight, Shawwal 1 will begin on Friday - signalling the first day of Eid Al Fitr.
