Ooops forgot to put one more question. Anyway this is a bit long. ^^

' this map shows which parts of the world are having its daytime and which parts are having

its nighttime.'

I know this sounds pretty weird, please tell me the wrong bit and how I can improve this

sentence. ^^ THANX GUYS
Hi JK,

'This map shows in which parts of the world it is day and in which parts it is night.'
Another alternative:

This map shows the distribution of day and night throughout the world.
