Is 1 Suro the Same as 1 Muharram? Here's the Historical Explanation

Questions regarding whether 1 Suro is the same as 1 Muharram frequently arise during the transition to the new year. According to the calendar, both indeed fall on the same day, yet they possess different historical backgrounds, cultural identities, and methods of celebration.

Technically, 1 Suro is the first day of the Javanese calendar, whereas 1 Muharram is the first day of the Hijri (Islamic) calendar. The following provides an in-depth explanation regarding the connection between the two.

The temporal alignment between 1 Suro and 1 Muharram is not a coincidence, but rather the result of a strategic policy by Sultan Agung Hanyokrokusumo, the King of Mataram Islam, in 1633 AD (1555 Saka).

At that time, Javanese society used the solar-based Saka calendar, while Muslims used the lunar-based Hijri calendar. To unify his people and strengthen the spread of Islam in Java, Sultan Agung created the Javanese Calendar.

Sultan Agung transformed the solar-based Saka dating system into a lunar-based system, following the Hijri system. This decision ensured that the beginning of the Javanese year (1 Suro) would always coincide with the beginning of the Islamic year (1 Muharram).

Despite falling on the same date, there are fundamental differences in how these two moments are perceived:

The word “Suro” actually originates from the Arabic word, Ashura, which refers to the 10th of Muharram. In Islamic tradition, the Day of Ashura is a highly sacred day encompassing various historical events of the prophets.

Javanese society subsequently adopted this term to name the entire first month of the Javanese calendar. Consequently, the month of Muharram is more commonly known as the month of Suro among the Javanese people.

So, is 1 Suro the same as 1 Muharram? The answer is yes in terms of chronological dating, but they differ in cultural context. 1 Suro represents a form of cultural acculturation between local Javanese values and Islamic teachings, initiated by Sultan Agung to create harmony within society.
