To me, Paul's example is a datetime operation: you start with a datetime 
(7am today), perform arithmetic on it by adding a period of time (one 
day), and get a datetime as the result (7am tomorrow).

To my naive mind, I would have thought of calendar operations to be 
things like:

- print a calendar;
- add or remove an appointment;
- send, accept or decline an invitation

What do you think calendar operations are, and how do they differ from 
datetime operations? And most importantly, how can we tell them apart?

Thanks,
