A year is a unit of time measuring Earth’s orbital revolution around the Sun. A common year consists of 365 days, while a leap year consists of 366 days. In scientific contexts, a year often refers to the Julian year, defined as exactly 365.25 days. The year is used to measure long-term intervals such as age, financial periods, and astronomical cycles. The year is abbreviated using the symbols y or yr (e.g. 451 y or 451 yr).

A month is a unit of time used in calendars, traditionally based on the approximately 29.5-day cycle of the Moon’s phases (a lunation). In the Gregorian calendar, a month is one of 12 divisions of a year and can last 28, 29, 30, or 31 days. A year contains 12 months, and each month typically represents about four weeks. The month is abbreviated using the symbol mo (e.g. 5412 mo).
