Eid-ul-Fitr is the Muslim day of celebration (similar to Christmas). It comes right after the month of Ramazan (where we fast for 30 or 29 days from sunrise to sunset).

On this day, Muslims all over the world exchange greetings, gifts and rejoice with their friends and family. We also give charity (zakkat) to the poor so that they too could enjoy the blessings of this cheerful day. So Eid Mubarak [Happy Eid] to all :)
