New moon is counted as the end of each month and has twelve months in total. The concept of era in Meitei calendar was first developed by Emperor Maliyafam Palcha, in the year 1397 BC (Palcha Era) in the realm of Kangleipak in present-day Manipur. It is believed that the 2nd, 3rd,  4th, 6th and 7th months of the Meitei calendar were named after Poireiten's agricultural activities. Similar to Gregorian calendar, the Meitei calendar also consists of twelve months and seven days but the starting date with the Gregorian calendar is different.
