how many hours, minutes or seconds would need to be taken away from our days to make February 29th permanent?

Answer 1

I don't know *BUT* what an interesting question.☼

Answer 2

A year is about 365.24219 days, so you would have to subtract 0.24219 days every year. Dividing that by 365 says you need to subtract 0.000663534 days or 57.3 seconds per day.

But if you hate daylight savings time now, just imagine the problems with making the day almost 1 minute shorter. In reality, we cannot control how fast Earth rotates or how long a real day is, all we could do is have our clocks run at a different speed from the rotation of the Earth. The "clock" day would not be equal to the real day defined by the rising and setting of the Sun. Sunrise would come 1 minute later each day, so after 2 months it would rise about an hour late, after a year it would rise about 6 hours late and after 2 years it would rise about 12 hours late. You would have to get up at sunset and go to bed at sunrise for months in a row, about once every 4 years. It would be horrible!

Answer 3

Given that it occurs every 4 years now, the total number of seconds is 126,230,400 per 4 years or an average of 31,557,600 seconds per year. Divide that result by 366 and you get 86,223 (rounded for whole seconds), or roughly 177 seconds off of the typical 86,400 second day. So we would have to lose almost 3 minutes a day to make this change.

Answer 4

Do you mean, have Feb 29 every year?
I calculate this considering the full leap-year rule, with no leap-year on century years unless they are divisible by 400. I get a value of 2 minutes, 58.819672131 seconds.

After 242 days, 12 noon would be in the middle of the night.

Answer 5

It depends what you mean.

I'll try 2m 59s with this approach.

For example, over a 400 year period (say from Jan. 1, 2001 to Jan 1, 2401), our calendar has 97 leap years (2100, 2200 and 2300 will not be leap years).

303 years with 365 days plus 97 years with 366 days, for a total of 146,097 days.

You want it to be 400 years of 366 days, for a total of 146,400 days. Therefore, each of the present days must be a tiny bit shorter, in order to fit 146,400 new days in the period where we used to fit 146,097.

The duration of the new day will be: 24 hours times (146097/146400) = 23h 57m 01.18s (using the present units of time)

or, if you prefer, you need to make clocks move a tiny bit faster, by a factor of (146400/146097) = 1.002074...
(one fifth of one percent)

Thus if both old and new clocks show 0:00:00 at the beginning of Jan. 1, 2001, then Jan. 2 will begin (in your new calendar) when your new clock changes from 23:59:59 to 0:00:00 (at which time, the old clock will show 23:57:01).

Each day will begin 2m59s sooner than the one before (compared to the mean solar time) so that by June, the day will change at lunch time.

Answer 6

Feb. 29trh is peremanently every 4th year. You can't change the length of a day without screwing everything up.The length of wa day is determined by the motions of the earth. If, you took away some seconds from the length of a day, the sun would rise and set earlier each day.

Answer 7

do the math, there are 365 days a year (3 times) and 366 days a year during leap year.

Answer 8

Beats me.

But I think it would just be easier to leave leap year as it is. It works out quite nicely.

Answer 9

Couldn't happen, time would catch up with us. After a while it would be dark during the day and light at night.

Answer 10

it would take subtracting 3.9452054794520547945205479452055
minutes per day for a single year to add an extra day
