Year

A year is a unit of time equal to the duration of one complete orbit of the Earth around the Sun. In the Gregorian calendar, which is the most widely used calendar system, a year consists of 365 days, or 366 days in a leap year (every 4 years), to account for the additional 0.2425 days in the Earth's orbital period.

Origin:

The concept of a year is tied to the Earth's revolution around the Sun, which takes approximately 365.2425 days. Early civilizations, such as the Babylonians and Egyptians, recognized the annual cycle of seasons and developed calendar systems based on the Earth's orbit. The Julian calendar, introduced by Julius Caesar in 45 BCE, divided the year into 12 months and established a leap year every 4 years. However, the Julian year was slightly too long, so the Gregorian calendar, introduced by Pope Gregory XIII in 1582, corrected this by shortening the average year to 365.2425 days, and refined the leap year rule to keep the calendar year in sync with the solar year. This calendar system is now the global standard.

Millennium

A millennium is a unit of time equal to 1,000 years. It is often used to refer to significant periods in history, typically for marking major events or changes over a long duration.

Origin:

The term "millennium" comes from the Latin word "mille", meaning thousand, and "annus", meaning year. The concept of a millennium as a period of 1,000 years has been used for centuries, particularly in religious and historical contexts. In Christianity, the idea of a "millennium" is notably mentioned in the Bible, particularly in the Book of Revelation, where it refers to a future period of 1,000 years of peace and righteousness. Over time, the term has been adopted in secular contexts as well to mark significant epochs or to refer to the transition between two distinct periods, such as the shift from the 1st to the 2nd millennium or the turn of the 21st century. Today, the millennium is often used to highlight key historical milestones, changes in culture, or technological advancements across a thousand-year span.
