February 30th – does this day exist?

Few people know that there aren't 24 hours in a day, but 23 hours, 56 minutes, and 4 seconds. This is the main reason for the creation of a leap year, when February 29th is added every 4 years. I decided to calculate the time by dividing it into two scenarios: 1) the number of seconds in a year if we assume there are 24 hours in a day, and 2) the number of seconds in a year if we assume there are 23 hours, 56 minutes, and 4 seconds in a day. Results of the First Calculation: - There are 86,400 seconds in one day. There are 31,536,000 seconds in a year. There are 31,622,400 seconds in a leap year. In 4 years, the total number of seconds is 116,230,400. Results of the Second Calculation: - There are 86,164 seconds in one day. There are 31,449,860 seconds in a year. There are 31,536,024 seconds in a leap year. In 4 years, the total number of seconds is 115,885,604. Results of Comparing the 1st and 2nd Results: - The difference in the total for 4 years is 344,796 seconds (slightly more than 4 days). After 4 years, we are given 344,796 seconds of life that we didn't actually live. This means that having a leap year every 4 years is incorrect, because for the most accurate timekeeping, a leap year should be held every 16 years. Using simple mathematical calculations, I found that each year, we are given 86,199 seconds, which is 35 seconds more than in one day, meaning that each year, we are given an extra day of life that doesn't exist. This raises the question: why isn't February 29th held every year? If February 29th were held every year, the need for a leap year would require it to be held every 7 years. And every seven years, a day called February 30th should be held. If we increase the number of summed years, the difference in the total will decrease by 10.7777777... until the official leap year, where the number of added seconds will be restored and become equal to 86,199 seconds. That is, every fifth year, the decreasing added day is restored. This means that in the first year, we are given 86,199 seconds (35 seconds more than a day), in the second year (rounded values) 86,189 seconds (25 seconds more than a day), in the third year (rounded values) 86,179 (15 seconds more than a day), and in the fourth year (rounded values) 86,169 (5 seconds more than a day). And in the fifth year, this number becomes equal to 86,199 seconds again. If February 30th is held every 7 years, then we are given 80 seconds for 4 years, and 155 seconds for 7 years. To reduce the added seconds and achieve the most accurate timekeeping, a NEW leap year should be held every 555,896,774,193,548,387,096,774,193,548,390 years (rounded to 556 years). Conclusion: it is necessary to reconsider the calculation of time and hold a leap year every 16 years, or hold February 29th every year and February 30th every 7 years, that is, hold a leap year every 7 years. But in any case, a New Leap Year should be held every 556 years. I calculated all of this tonight. People, let's discuss the idea of February 30th.
