In the Julian calendar, the vernal equinox moved gradually away from 21 March. The Gregorian calendar reform restored the vernal equinox to its original date, but since the festival was by now tied to the date, not the astronomical event, Kha b-Nisan remains fixed at 21 March in the Julian reckoning, corresponding to 1 April in the Gregorian calendar. The Vernal equinox is celebrated throughout Greater Iran as Noruz on 21 March. However, in the ancient Assyrian, Akkadian and Babylonian traditions, the spring festival was celebrated in the first days of the month known as "Nisan" and the calendar adopted by the ancient Assyrians had the month "Nisan" at the beginning of the calendar lending to the term "Kha b-Nisan", or the "first of Nisan". In the 1950s, a rising upsurge in Assyrian nationalism resulted in the creation of an official "Assyrian calendar" with its era fixed at 4750 BC, inspired by an estimate of the date of the first temple at Ashur in the Middle Ubaid period. In the same spirit, the Akkadian name of the spring festival, Akitu, was revived. It is essential to consider that the Assyrian people have generally celebrated Akitu on the first day of April since 4750 BC and that a creation of an official calendar would aim to unite the Assyrians in their nationalism. The event is also largely celebrated by Assyrians residing in Syria. Although the Syrian government does not acknowledge the festival, Assyrians still continue with the celebration. In 2002, Assyrians in Syria celebrated the event with a mass wedding of 16 couples and over 25,000 attendees. After the formation of Turkey, Kha b-Nisan along with Nowruz were banned from public to celebrate. Assyrians in Turkey were first allowed to publicly celebrate Kha b-Nisan in 2005, after organisers received permission from the government to stage the event, in light of democratic reforms adopted in support of Turkey's EU membership bid. Around 5,000 people "including large groups of visiting ethnic Assyrians from Europe, Syria and Iraq" took part in the Kha b-Nisan celebrations. One of the largest Assyrian New Year celebration took place in Iraq in 2008. Public celebrations were not allowed by Saddam Hussein's regime prior to the start of the Iraq war. The event was organized by the Assyrian Democratic Movement and between 45,000 and 65,000 people took part in the parade. In 2004, Hon. George Radanovich of the California State Assembly recognized the Assyrian New Year and extended his wishes to the Assyrian community in California. This was later followed by a letter from the California governor, Arnold Schwarzenegger, to the Assyrian community in California congratulating them on the annual celebration.
Celebration
Assyrians celebrate Kha b-Nisan by holding social events including parades and parties. They also gather in clubs and social institutions and listen to the poets who recite the story of creation. The men and women wear traditional clothes and dance in parks for hours. It has also become tradition to hold a parade down King Sargon Blvd in Chicago, Illinois, with the Assyrian organizations, churches, and sometimes businesses, each creating a float and participating in the parade. It is a tradition in Assyrian villages for girls to gather flowers and herbs which are then suspended under the house's roof. The bunches are referred to as "Deqna d-Nisan", meaning "the beard of April/Spring".
