I think because minutes and hours can easily be composed by multiplying

That's an argument that timedelta should *not* have a 'days' attribute,
because a day is not a fixed number of seconds long (to know how long
a day is, you have to know which day you're talking about, and where).
It's an undocumented feature of timedelta that by 'day' it means '86400
seconds'.
When you're working only with dates, timedelta not having a 'days'
attribute would be annoying, especially when you consider that a day is
usually 24 hours, but sometimes 23 or 25 hours (DST).
