Hello again;

I am having some confusion about a solar calendar I am making. That is how to deal with leap years.

I think if I include Feb. 29th on my solar calendar and align the calendar on a leap year the shadows will be off 1/4 day each year for 4 years when it will self correct on the next leap year. Is that right?

I also think if I align my calendar to be correct halfway between the leap year cycle that the shadows will only be off a maximum of 1/4 day each year for 2 years when the shadows will start to be off 1/4 day each year in the other direction. Also self correcting if I include Feb. 29th.

I wonder if I don't include Feb 29th if my calendar would get progressively worse each year....1/4 of a day a year error compounded, so in 100 years my calendar would be off 25 days? If that is correct thinking, in 1,460 years (365 x 4)my calendar would be off 365 days, or in other words self corrected.

I suppose all would be fine except I would have lost a year.

Has the leap year problem been solved with solar calendars?

The hard part for me to grasp is that my "real" days are always full days, I don't ever have a quarter day.

thanks again for any help
