Our multi-calendar date converter serves a wide range of users:
The Gregorian calendar, also called Miladi in Persian and Arabic, is the world's most widely used civil calendar. Introduced by Pope Gregory XIII in 1582, it's a solar calendar with 365 days in a common year and 366 in leap years. This calendar is used for international business, legal documents, and daily life in most countries.
The Shamsi calendar, known as the Afghan calendar or Persian solar calendar, is used in Afghanistan and Iran. It's a solar calendar that begins from the year 622 CE (the Hijra year). The first six months have 31 days, the next five have 30 days, and the last month has 29 or 30 days depending on leap years.
The Persian calendar uses the same astronomical calculations as the Shamsi calendar but with Persian month names (Farvardin, Ordibehesht, Khordad, etc.). It's the official calendar in Iran and is identical to the Afghan Shamsi calendar in terms of date calculations.
The Islamic calendar, also called Hijri or Qamari calendar, is a lunar calendar used by Muslims worldwide. It has 12 lunar months totaling approximately 354 days, making it about 11 days shorter than the solar year. This calendar is essential for determining Islamic holidays, Ramadan, and religious observances.
The Julian calendar was introduced by Julius Caesar in 45 BCE and was used until the Gregorian calendar replaced it. It's still used by some Orthodox churches and for astronomical calculations. The Julian calendar has a simpler leap year rule than the Gregorian calendar.
The Hebrew calendar is a lunisolar calendar used by Jewish communities worldwide. It has 12 or 13 months per year, with leap years adding an extra month. This calendar is used to determine Jewish holidays, religious observances, and cultural events.
The Kurdish calendar is a solar calendar similar to the Persian calendar, used by Kurdish communities. It follows the same astronomical calculations as the Shamsi calendar but uses Kurdish month names.
A Julian Day Number is a continuous count of days since noon on January 1, 4713 BCE in the Julian calendar. Astronomers, historians, and researchers use JDN for precise date calculations because it provides a single number that represents any date, making it easy to calculate the difference between dates. Our converter allows you to convert between JDN and any calendar system.
