This year the new year was 2 midnight, next year it will be in the morning the next year it will be around noon and so on. Every 4 years the calendar has 366 days, Since the extra 5 hours add up. The 366 day year is called the intercalary “Kabise” year. Each of the Zodiac signs correspond to one of the 12 months in this calendar.

In 1925 the Iranian parliament changed the official calendar from loner Hijri to Solar Hijri calendar and it has been used since. All Iran’s ancient ceremonies and historical holidays are based on this calendar.
The month names in this calendar are based on the old religion of Iran. The 10th month is named “Dey” refers to “Ahuramazda” the God of the Goodness and brightness. The other 11 months are names of angels and forces who help Ahuramazda.

Loner Hijri Calendar:
This calendar is based on the moon circulation, it is known as the Islamic calendar which is the social calendar of Muslims. Islamic rituals and prays such as fasting, haj and ceremonies are all based on the months of this loner calendar. The origin of this Calendar is prophet Mohammed’s Hejira (travel) from Mecca to Medina. The year starts with month of Moharam.
While the Solar Hijri calendar is very similar to the western calendar, the loner calendar is very different. This year consists of 12 months that are either 29 or 30 days long. This year has only 354 days, which means it moves 10 days back every year. It does not comply with the natural seasonal changes, which means if Ramadan is in summer this year in 15 years Ramadan will be in winter. In this calendar the start of the day is when the moon comes into the sky. There for on religious events, the praying rituals start on sunset of the previous day and finish around noon the next day.
The month starts with the sight of the moon seen in the night sky. Some countries such as Iran only accept the start of loner months with human sight of the moon. Some countries base it on calculations. In Iran there are professional moon sighting groups that are deployed on beginning and end of the month of Ramadan, which cases controversy every year.
The months of loner year consist of : Moharam, Safar, Rabiolaval, Rabiosani, Jamadioaval, Jamadialsani, Rajab, Shaaban, Ramadan, Shaval, Zighade, Zihaje.
This calendar is also solar, which has 12 months of 30 or 31 days, except Feruary which is 28 days. This calendar is based on the ancient Roman calendar that has gone through many changes throughout the centuries. The name of week days which still stand are based on planets and moons.

How 3 calendars are necessary in Iran:
Printed calendars in Iran have all these 3 dates on one page. Official events, such as national holidays are in the solar hijri calendar. The religious ceremonies are in the loner Hijri calendar, which move 10 days back every year, therefor they can’t be easily incorporated into the solar hijri calendar. Many prays and rituals have to be practiced on exact dates of the loner calendar. Religious Muslims know the exact dates very well. The western calendar is used in any foreign affairs; business; foreign travel etc. Therefor all these dates are necessary in calendars in Iran on a daily bases for most Iranians.
