Days between dates based on 365-day year
returns
the number of days between NumDays
= days365(StartDate
,EndDate
)StartDate
and EndDate
based
on a 365-day year. All months contain their actual number of days.
February always contains 28 days.
If EndDate
is earlier than StartDate
, NumDays
is
negative. Under this convention, all months contain 30 days.
Either input argument can contain multiple values, but if so,
the other must contain the same number of values or a single value
that applies to all. For example, if StartDate
is
an n-row character array of date character vectors,
then EndDate
must be an N
-by-1
vector
of integers or a single integer. NumDays
is then
an N
-by-1
vector of date numbers.
