What is a Common Year?
A common year is a year that has 365 days. This is different from a leap year, which has 366 days. Leap years happen almost every four years to keep our calendar in sync with the Earth's orbit around the sun.
This specific type of common year, which starts on a Thursday, has 53 weeks if you follow the ISO 8601 week format.
