According to Google, Leap Day 2024 - February 29 - only occurs every four years to ensure the calendar is in line with the Earth's orbit around the Sun. The reach of Google's Leap Day Doodle on February 29, 2024 is global.
To celebrate the leap year of 2024, the February 29 Doodle depicts the number 29 in the middle of the Google logo as a frog. The number is placed between the numbers 28 and 1, representing the leap day in February (which has 28 days).

According to the Gregorian calendar, the standard calendar currently used throughout most of the world, it takes the Earth about 365.25 days to complete one revolution around the sun. By convention, a year has 365 days, so each year will have an extra 0.25 days, or 6 hours, 4 years will have an extra day or 24 hours, and a century (100 years) will have an extra month.
To avoid these errors, calendar makers have agreed to add one day to February every four years. That day is called a leap day, and years with a leap day in February are called leap years.
According to the lunar calendar, a month has 29.53 days, so a lunar year will be rounded to 354 days, 11 days less than the solar calendar. So 3 years will be 33 days less, this time will accumulate into a month. Therefore, after 3 years according to the lunar calendar, we will have an extra month, the extra month added to the leap year is called a leap month, so that the lunar year and the solar calendar do not differ much.
Calculating a leap year is very simple. According to the solar calendar, every 4 years there will be 1 leap day, so take the year number and divide it by 4. If there is no remainder, that year is a leap year.
According to the calculation of the lunar calendar, according to the ancients, every 19 years, there is an extra leap month every 2 years. With this calculation, there will be 7 extra leap months, placed in the 3rd, 6th, 9th or 11th, 14th, 17th, 19th years of the 19-year cycle.
Therefore, to calculate a leap year, we just need to take the solar year and divide it by 19. If it is divisible or gives a remainder of 3, 6, 9, 11, 14, 17, then that lunar year will have a leap month.
Google Doodles are variations of the Google logo with temporary replacements for the logo on Google's homepage to celebrate holidays, events, achievements and people.
Instead of having to keep the traditional logo, Google Doodle is now born to transform into vivid images with certain meanings. This is to help users have more fun when using Google's search engine.
