The most ancient traditions of Islam are going high-tech, with a slew of modern offerings for those observing the holy month of Ramadan, which begins this week. Cell phone applications such as "iPray" or "iQuran" offer a beeping reminder of requisite prayer times, while the "Find Mecca" and "mosque finder" programs help the Muslim traveler in an unfamiliar city find the nearest place to pray. The applications aren't just for Ramadan; there are Islamic-themed programs that help users find the nearest Costco offering foods prepared according to Islamic dietary rules, learn the correct Arabic pronunciations in a daily prayer, or count how many pages of the Quran they've read that day -- all on a mobile phone. The dates of Ramadan still are determined by the lunar calendar, and calculations can differ among Islamic communities around the world. In North America, many Muslims will mark the first day of Ramadan on Wednesday. But Islam never has been at odds with innovation, said Zinnur Tabakci, who runs an Islamic religious book and gift shop in Paterson, N.J. "Islam is not against technology. Now you can do it easier, faster," said Tabakci, who recently supplemented the strings of traditional prayer beads and religious texts he sells with a wall of mobile phone accessories to keep up with demand.

The exact dates of the start and the end of Islam's holy month Ramadan depend on the sighting of the new moon. Muslims observe the ninth month of the lunar Islamic calendar by abstaining from food, drink and sex from dawn until sunset during Ramadan. The fast is one of the five pillars of Islam.
