Why does the calendar shift one day each year?

Answer 1

The calendar shifts one day each year due to the discrepancy between the solar year (365.24 days) and the calendar year (365 days). To account for this, we have a leap year every four years, adding an extra day to February. This adjustment helps keep our calendar in alignment with the Earth's orbit around the sun.

Answer 2

Oh, dude, the calendar shifts one day each year because of the way we've set up our system of tracking time. Basically, a year isn't exactly 365 days, so we have to add in an extra day every four years to catch up. It's like a little time adjustment so we don't end up celebrating Christmas in July or something.

Answer 3

I assume you mean something like "why was Dec 31 a Wednesday last year and a Thursday this year"? There are 365 days in a year, however this does not divide evenly with the number of days in a week. 7 days/week x 52 weeks = 364 days. Therefore there's an extra "day of the week" added each year. On leap years an additional day is added.
