Leap years keep our calendars in check! Allow us to explain why leap years are necessary and share some of the fun folklore surrounding them. Simply put, a leap year is a year with an extra day—February 29—which is added nearly every four years to the calendar year. Without this extra day, our calendar and the seasons would gradually get out of sync. Keep reading for a longer explanation.
Because of this extra day, a leap year has days instead of Additionally, a leap year does not end and begin on the same day of the week, as a non—leap year does. Generally, a leap year happens every four years, which, thankfully, is a fairly simple pattern to remember. However, there is a little more to it than that. The short explanation for why we need leap years is that our calendar needs to stay aligned with the astronomical seasons.
