Discover how a leap year keeps our calendar aligned with Earth's orbit by adding February 29 every four years to prevent seasonal drift.

A leap year affects us by keeping our calendars in alignment with the Earth's revolutions around the sun. It adds an extra day, February 29, every four years. This adjustment helps correct the discrepancy caused by the Earth not orbiting the sun in precisely 365 days, preventing seasonal drift over time.

FAQs & Answers

  1. Why do we have a leap year every four years? A leap year occurs every four years to add an extra day (February 29) to the calendar, compensating for the fact that Earth's orbit around the sun takes approximately 365.25 days, not exactly 365.
  2. What would happen if we didn't have leap years? Without leap years, our calendar would gradually drift out of alignment with Earth's seasons, causing seasonal events like solstices and equinoxes to shift over time.
  3. How does February 29 help keep the calendar accurate? February 29 adds an extra day approximately every four years, correcting the roughly 0.25 extra days each year that aren't accounted for in a standard 365-day calendar.
