Surprised by this error from time and date .com the earth does not rotate once every 24H of course, that's the time it takes for the sun to be back in the same position (mean solar day) the earth rotates once every sidereal day 23h 56m 4s (minus the 1.55ns)

It's not even the time until the sun returns to the same position in the sky, since the earth's orbit is not a circle.
Yep, this is because the earth spins the same direction as its rotation around the sun. So each year, there’s a discrepancy of one day.

And 24 hours / 365 = about 3.9 minutes of discrepancy per day.

I picked up on that too. I generally expect that type of simplification in non-technical articles geared toward the general public. But this one was specific enough that I think it deserved a mention.
