Hello, everyone.

Please assume(imagine) that it's June the 2nd today.
'We're having a meeting
on June the 5th.'
Instead of the expression underlined above, can I say :
'We're having a meeting
in three days. (or
in three days' time)' (I think these are both fine.)
Yes.
'We're having a meeting
three days from today.' (I'm not sure about this one.)
Yes
'We're having a meeting
three days later.' (I'm not sure. Is 'from today' understood by the person I'm talking to?)
No, this doesn't work.
'We're having a meeting
three days later from(than?) today.' (I don't think it is OK.)
No.
If there are any other possibilities, could you be so kind as to tell me about them?
Thank you in advance.
