A leap year occurs almost every four years to keep our calendar in sync with the Earth's orbit around the Sun. A common year has 365 days, but a leap year has 366 days, with the extra day added to February (February 29th). This extra day is crucial for date calculations spanning multiple years, as it subtly affects the total number of days and thus the precise year difference. The Years Calculator implicitly accounts for these, ensuring accuracy.

Centuries, Decades, and Eras ⏳

A year is a fundamental unit, but it aggregates into larger time periods:

• A decade is a period of 10 years.
• A century is a period of 100 years.
• A millennium is a period of 1,000 years. These larger units are often used in historical analysis, demographic studies, and long-range forecasting. While the years calculator gives results in individual years, it forms the basis for understanding these broader spans.

Fiscal Years vs. Calendar Years 🏦

As discussed in previous contexts, a calendar year runs from January 1st to December 31st. A fiscal year, however, is a 12-month period used for financial and business planning, which can begin in any month. For example, a company might have a fiscal year from July 1st to June 30th. While the Years Calculator primarily operates on calendar years, its ability to accurately project dates into the future or past can still support fiscal year planning by providing the correct calendar date for a specific year increment.
