UniCal - Calendar Converter

Would like to know your birth date in the French Revolution calendar?
What was the Islamic date on the day of your wedding? What is the celebration for tomorrow in the Chinese calendar?
Would you like to be alerted each day with the saint of the day?

This app converts any given date into the corresponding Gregorian (most common), Buddhist, Chinese, Coptic, Ethiopian, Hebrew, French Republican, Maya, Islamic or Persan calendars. It also can create daily alerts for the celebrations for each calendar.

The app includes active web links for details on calendars, saints, symbols, zodiac and various date elements of the calendars.
