AN AUTOMATIC TIME SYNCHRONIZATION SYSTEM FOR THE ISLAMIC AND GREGORIAN CALENDARS

摘要

This invention relates to an automatic time synchronization system for the Islamic and Gregorian calendars. It shows accurately the date (by year, month, and day) and time (by hours, minutes, and seconds) according to the Gregorian calendar (the solar year), as well as the corresponding date and time according to the Islamic calendar (the lunar year). The system also shows crescent shape and size during the days of the lunar month, and the corresponding date according to the Gregorian calendar. In this way, the system calculates time precisely according to both Gregorian and Islamic calendars for thousand years past, and thousand years to come.
