Month to Year Converter

A month is a unit of time originally based on the lunar cycle, now standardized as approximately 1/12 of a year or about 30.44 days on average. It serves as an intermediate time measurement between weeks and years for planning and organization.

Months originated from ancient observations of lunar cycles, with early calendars based on the approximately 29.5-day lunar month. Modern months were standardized with the Roman calendar and later the Gregorian calendar, creating the current system of 12 months with varying lengths.

Months are extensively used for medium-term planning, billing cycles, financial reporting, project timelines, and organizational scheduling. They're standard for business planning, subscription services, rental agreements, and administrative time periods.

A year is a unit of time representing the period required for the Earth to complete one orbit around the Sun, approximately 365.25 days. It serves as the fundamental long-term time measurement for calendars, planning, and astronomical calculations.

The year has been used as a time measurement since ancient civilizations observed seasonal cycles and celestial movements. It became standardized with the development of various calendar systems, with the Gregorian calendar establishing the modern 365-day year with leap years every four years.

Years are universally used for long-term planning, historical dating, age measurement, financial planning, and astronomical calculations. They're fundamental to calendar systems, legal documents, contracts, and any application requiring long-term time references.
