30 days

180 days

365 days

The time it takes for the Earth to complete one full revolution around the sun is approximately 365 days. This period defines a year in the Gregorian calendar, which is the calendar system most commonly used today. The Earth's orbit around the sun is not a perfect circle but an ellipse, and the completion of this orbit marks the cycle of seasons and is critical for understanding timekeeping and calendars. The length of a year is also related to the position of the Earth and how it experiences changes in climate and day length throughout the year.
