How do you exactly do that?
Like if I have two dates as std.datetime.DateTime
How will I get the months or years between the two dates?
I was surprised to learn that Duration does not support them
and only has weeks, days etc. but not months or years.
I can't seem to find any standard way of doing it.
Will I have to calculate that myself or? I feel like that's a
big thing missing if it's not there already.
My use-case is simple. I need to calculate years/months since
a specific date has happened.
A month doesn't have a specific amount days/weeks so "what is a
month" cannot be answered from just the duration alone. You can
use SysTime.diffMonths or DateTime.diffMonths to calculate the
number of months between two dates. Years are always 12 months
so you don't have to worry there and can just divide by 12
If you also want days or weeks, you will need to calculate that
yourself afterwards
Yah if you saw my second reply that's what I said I found.
It did exactly what I needed it for.
What I was hoping for originally was that the duration had some
"date" knowledge but that was just me being optimistic but as
diffMonths solves the problem then there is no issue.
