Length of Tropical Years 1900–2100

A tropical year is approximately 365.242189 days long. However, the exact length can vary up to 30 minutes.

A tropical year is also known as a solar year, an astronomical year, or an equinoctial year. It is defined as the time it takes to complete a full seasonal cycle. Because the Earth's speed is not constant, the length of tropical years can vary by up to 30 minutes.

The length of a tropical year is usually measured from one equinox or solstice to the next. The table below shows the exact time spans between the March equinoxes in the years 1900 to 2100.
