Common year starting on Tuesday facts for kids

This article is about a special kind of calendar year: a common year that starts on a Tuesday. A common year is a regular year with 365 days, unlike a leap year which has 366 days. If January 1st of a common year falls on a Tuesday, then the whole calendar for that year will follow a specific pattern. This pattern is identified by something called a dominical letter, which for these years is F.

Some examples of Gregorian years that fit this pattern are 1974, 1985, 1991, 2002, 2013, 2019, and 2030. In the Julian calendar, years like 2014 and 2025 also start on a Tuesday.

What is a Common Year?

A common year is a regular year that has 365 days. Most years are common years. Every four years, we have a leap year, which has an extra day (February 29th) to keep our calendar in sync with the Earth's orbit around the Sun. But in a common year, February only has 28 days.

Why Calendars Repeat

Because common years always have 365 days, their calendars repeat in a cycle. If a common year starts on a Tuesday, the next common year that also starts on a Tuesday will have the exact same calendar layout. This is why we can list many years that share the same calendar pattern.
