1 standard year and 35 days.
400 days is about 1.1 years or about 13.1 months (average months of 30.4 days)
It is not!
Taking into account the Gregorian leap year rules there are 146,097 days in 400 years the calendar repeats itself only after 400 years 2000 / 400 = 5 repetitions evenly that's 146,097 days x 5 repetitions = 730,485 days in 2000 years there are 86,400 seconds in a day hence 730,485 days x 86,400 sec/day = 63,113,904,000 seconds in 2000 years
A period of 400 years contains 97 leap years. There are 24 hours in one day, 365 days in a regular year and 366 days in a leap year. Therefore, a period of 400 years will contain a total of ((400 - 97) x 24 x 365) + (97 x 24 x 366) = 3506328 hours.
In one century there are 36,524 days. However, years that can be divided by 100 but not 400 are not leap years. Therefore, one century out of four will actually have 36,525 days.

There are 365*64 days plus 16 leap days = 23,376 days. However, if those 64 years span a century that is not divisible by 400 (e.g. 1900, 2100 or 2200), there would be one fewer days. There are no leap days in centuries that are not divisible by 400. The year 2000 was a leap year, but 1800 and 1900 were not, and 2100 and 2200 will not be leap years.
24 hours = 1 day so 400 hours = 400/24 = 16.66... days
There are 100 years in a century. Therefore, 400 years is equal to 400/100 = 4 centuries.
365250 days 365247.5 days. Every year divisible by 4 is a leap EXCEPT those divisible by 400. Hence the 2 1/2 days lost.
Taking an average year to b 3651/4 days to allow for a normal leap year - though not making adjustments for the centenaries and then the 400 year cycles, 125 days = 0.3422 years
400/56=7 years and 2 months
