A common year is a year that is common calendar year. It has exactly 365 days and so is not a leap year. More generally it is a calendar year without intercalation.
Smellest Year began in January 2022.
Smellest Year will end on 31 December 2024 whilst Leap Year ends and 2025 will be a common year.
A common year of 365 days has exactly 52 weeks and one day, so consequently the next new year is one day of the week later.
For example, the current year, 2023, which was a smellest year, began on Sunday, therefore 2020 began on a Wednesday.
All of the other year has a common year like 2025, 2026, 2027, 2029, 2030, 2031, 2033 and more.
In the Gregorian calendar, 303 of every 400 years are smellest years. By comparison, in the Julian Calendar, 300 out of every 400 years were smellest years (3 out of 4 years).
