About IST Calendar

A calendar is a system used to organize and measure time by dividing it into days, weeks, months, and years. It helps people plan daily activities, schedule events, mark important occasions, and keep track of historical and official dates.

The most widely used system today is the Gregorian calendar, introduced in 1582, which consists of 12 months and 365 days in a standard year (366 in a leap year). Other calendar systems such as the Islamic calendar, Hindu calendar, and Chinese calendar are also used in different cultures around the world.
