Muslims all over the world celebrate Ramzan Id also called Id-Ul-Fitr with great jubilation on the first day of the Islamic month Shawwal. This day marks the end of Ramadan, the 9th month of the Islamic calendar, in which the Holy Quran was revealed to Prophet Mohammed. Since the Islamic calendar is based on the moon, the month of Ramzan falls at different times each year. Muslims spend the whole month of Ramadan in fasting and penance. No food or drink is taken from sunrise to sunset on each day of the month. The completion of the month-long fast is determined by the appearance of the new moon, and is celebrated with enthusiasm as Id-Ul-Fitr, which means 'the fast is over'. In India, this Id is also called Mithi Id. The month-long fast culminating in this Id spreads a feeling of brotherhood. Muslims wear new clothes on this day, exchange gifts, participate in great fairs and watch stunning fireworks displays.
