Imagine you have a special paper that tells you what day it is and when important events are happening, like your birthday or when school starts. The Assamese people also have a special paper like this, called the Assamese calendar.
The Assamese calendar is different than the calendar we use in America. It was created a long time ago by a very smart group of people called astrologers. They looked at the stars and the movements of the sun and moon to figure out how many days there are in a year.
The Assamese calendar is based on the lunar cycle, which means it follows the phases of the moon. The moon goes through different phases, like a big light bulb that gets brighter or dimmer. The calendar starts with the first day of the month, when the moon is the most visible. Every month has a special name in the Assamese language, like "Bohag" for April or "Aghun" for August.
The most important day of the year for the Assamese people is called "Rongali Bihu," which means "festival of colors." It happens in April, when the crops are ready to be harvested. People dance, sing, and throw colorful powder on each other to celebrate.
The Assamese calendar also tells people when to celebrate other important events, like weddings or religious holidays. It is written in the Assamese language, so people who speak that language can read and understand it.
In summary, the Assamese calendar is a special paper that tells people in Assam what day it is and when important events are happening. It is based on the phases of the moon and was created by astrologers a long time ago. The most important day of the year is Rongali Bihu, when people celebrate the harvest with music and colorful powder.
