Day/Date Calculations
# The Setup screen can be used to specify
either a 365-day or 360-day year for financial
calculations. Day/date calculations are also
performed in accordance with the current
setting for number of days in the year, but the
following calculations cannot be performed
when the 360-day year is set. Attempting to do
so causes an error.
(Date) + (Number of Days)
(Date) – (Number of Days)
# The allowable calculation range is January 1,
1901 to December 31, 2099.
