An Islamic year consistently falls about 11 days short of the solar year.For that reason, the Islamic calendar cannot be used for agriculture or other activities traditionally linked to the seasons, and most Muslim countries officially use the Gregorian calendar as their civil calendar alongside the Hijri system. The traditional version of the Islamic calendar requires an authorized person or committee to make an actual sighting of the Crescent Moon to determine the length of each month.If no sighting is made, a 30th day is added to the current month, which is then followed by the first day of the subsequent month. The Persian and Islamic calendar systems are otherwise unrelated.The former is a solar calendar, so its year count differs substantially from that of the Islamic lunar calendar.You will then receive the dates in the other calendar.
Even though the Islamic calendar year does not match up with the length of a solar year, it does not feature a correction mechanism like leap days in the Gregorian calendar to make up for the deviation.The function of the Islamic Calendar Converter and Arabic Converter is very simple.You simply enter the dates that you know into the corresponding fields (Gregorian Calculator o Islamic Calculator) and you then press the calculate button.The 30 year cycle is consists of 19 years of 354 days and 11 years of 355 days.The Hijri calendar is not to be confused with the Solar Hijri calendar used in Iran and Afghanistan. The Islamic calendar is a lunar calendar whose time reckoning is tied to the Moon phases.Pre-Islamic time reckoning did not utilize year numbers as each year was identified by an important event that occurred in it.
