Grumpy_Mike:

Hm OK I had to consult The Oracle of Google on that, and I'm still happy to go with a day being how long it takes to spin once.

So you say because it is on the internet it is true?

No that's not what I meant. I consulted the Oracle to remind me of what I learned in geography c1970, which is what you said about the sidereal day, sidereal being a word I hadn't used since I first heard it afaik :wink: (I was taught the right stuff, just not the kind of thing I think about often, nearly 50y later)

I meant I'm not really fussed by 4 minutes here and there, and for my intents and purposes (I say "my"), if I think of the earth spinning once in 24 h, I won't lose any sleep over it.

Well, technically you might lose about 4 minutes/night of it..... :wink: Which is my excuse for being 15 minutes late to work every day...

Coincidentally 15 minuets is roughly the amount the actual sun's position can vary from the mean sun's position.
