The Tabarian Calendar is a calendar system used in some countries in the Middle East. It has 12 months, each with 29 or 30 days. The months are usually named after different seasons, such as spring, summer, fall, and winter. Every year starts with the month of Farvardin, which is usually the first month of spring. The new year starts on the first day of Farvardin, which is the first day of the Tabarian year. The Tabarian year has around 365 days, so it’s a bit shorter than the normal calendar year. It has been used in Iran and other Middle Eastern countries for thousands of years, and is still used in some countries today.
