If we have an extra day added every 4 years, then how come we are not noticing it?

Question

If earth’s rotation is 365,25 days this means that the first year December 31st at 23:59 will look like an early afternoon; on year 2 it will look like noon and year 3 it will look like a morning (since we have 18 hours to spare).

Answer 1

The Earth still _rotates) just the same around its axis making the day length, it is the _orbit_ around the sun making the year, we are correcting for. The earth does not complete the whole circle around the sun in 365 days, we need an extra day every 4 years to get it to roughly the right spot.
