Notice anything different about today? Let’s jump right into it!
This day occurs in every four years.
” Today’s Doodle is jumping for joy on Leap Day, the 29th day of February that only occurs about every four years, to keep our calendars in alignment with the Earth and sun.
We HOP you have a good one—Happy Leap Day!”-says Google Doodle
This particular date is added to those years that are divisible by 4. In case of a leap year, one extra day is added to calendars as that year in particular lasts for 366 days instead of 365.
The time required by the Earth to complete its orbit around the Sun is approximately 365.242 days. But years are usually only 365 days. To adjust for the extra 0.242 days in the orbital period, which becomes almost one full day in four years, the calendar adds an extra day once every four years. This approximates the time to 365.25 days, which is close to the actual 365.242 days
