Ramadan 1429 AH
According to authorities, today is the first day of the ninth month, Ramadan, in the Islamic calendar.
This is a brief description of the month of fasting and the reasons for it, with more details and links at Wikipedia.
Unfortunately, in recent years, Ramadan has signified an increase in violence in the Middle East.
[The site I normally reference for the timing of Ramadan has been hacked to download malware. That is unfortunate as it was a reliable source of the timing which requires a decision on the sighting of the crescent moon, and is not the same world wide.]
