Description

Calculates the TDateTime value that represents a specified day of the year for a specified year.

TryEncodeDateDay calculates the TDateTime value for the date specified by the AYear and ADayOfYear parameters.

AYear is the year. It can be any value from 1 through 9999 (inclusive).

ADayOfYear is the day of the year, where 1 is January 1, 2 is January 2, 32 is February 1, and so on.

AValue returns the specified date as a TDateTime value. The time portion of AValue is 0 (midnight at the start of the specified day).

TryEncodeDateDay returns True if AYear and ADayOfYear represent a valid date, and False if ADayOfYear is less than 1 or greater than the number of days in AYear.
