"سال" is the Persian word for "year." It is a unit of time that typically consists of 365 days, or 366 days in a leap year. The year is divided into twelve months, each varying in length. In the Gregorian calendar, which is widely used around the world, the months include January, February, March, and so on. In Persian culture, the new year is celebrated during نوروز, which marks the arrival of spring. This celebration occurs on the first day of the month of فروردین in the Persian calendar, usually around March 21. It symbolizes renewal and the start of a new year filled with hope and prosperity.
