Eid Mubarek

From Wikipedia:

"Current reports from various sources have estimated that 1.2 to 1.57 billion Muslims populate the world, or about 23% of an estimated 2009 world population of 6.8 billion..."

"Eid ul-Fitr, often abbreviated to Eid, is a Muslim holiday that marks the end of Ramadan, the Islamic holy month of fasting. Eid is an Arabic word meaning "festivity," while Fiṭr means "breaking (the fast)". The holiday celebrates the conclusion of the twenty nine or thirty days of dawn-to-sunset fasting during the entire month of Ramadan....

....Eid ul-Fitr is celebrated for one, two or three days. Common greetings during this holiday are the Arabic greeting ‘Eid Mubārak ("Blessed Eid") or ‘Eid Sa‘eed ("Happy Eid"). In addition, many countries have their own greetings based on local language and traditions. Muslims are also encouraged on this day to forgive and forget any differences or past animosities that may have occurred with others during the year....

Although the date of Eid ul-Fitr is always the same in the Islamic calendar, the date in the Gregorian calendar falls approximately 11 days earlier each successive year, since the Islamic calendar is lunar and the Gregorian calendar is solar. Hence if the Eid falls in the first ten days of a Gregorian calendar year, there will be a second Eid in the last week of the same Gregorian calendar year. The Gregorian date may vary between countries depending on the local sightability of the new moon. Some expatriate Muslim communities follow the dates as determined for their home country, while others follow the local dates of their country of residence. In the Islamic calendar, a new day, and therefore also Eid ul-Fitr, begins at sunset."
