Since 000 is not a real direction... (North is 360) ...,


360 and 0 are used interchangeably for North.



Well, yes and no. They mean the same thing, of course... but they are not
really "used interchangeably".

Direction 000 in a METAR is used to represent calm wind, not North wind.

I have never seen "00" painted on a runway.

Computer routines for calculating direction will often expect input and
normalize results into the 1-360 range, not 0-359.

Very rarely do you hear "... heading is 000" as opposed to "... heading is
360"

etc....
