 REMARKS
 * This function can accept values outside the normal range.* For example if you pass in the year 2020 and the month 14, it will return a date in the second month of 2021 (ie it will add 14 months).* You can specify relative dates for each argument using any numeric expression that represents some number of days, months, or years before or after a certain date.* When an argument exceeds the accepted range, it increments to the next larger unit as appropriate.* If any argument is outside -32,768 to 32,767, then an error occurs.* The "year" should be entered as a four-digit year.* If "year" is between 0 and 29, inclusive, are interpreted as the years 2000-2029.* If "year" is between 30 and 99 are interpreted as the years 1930-1999.* If "year" is between 0 and 99, inclusive, are interpreted as the years 1400-1499.* If "year" < 1, then this number is subtracted from the current year.* If "month" = 0, then it represents December of the previous year.* If "month" = 13, then it represents January of the next year.* If "day" = 29 and the month is February and its not a leap year, then this represents 1 March.* If "day" = 35, then it represents one month plus a certain number of day depending on the actual date.* If "day" = -1, then it represents November of the previous year.* A practical use of this function is to identify leap years << User Defined Function >>.* You can use the DATE function to return the current system date.* You can use the DATEADD function to return the date with a specified time interval added.* You can use the DATEDIFF function to return the number of a given time interval between two specified dates.* You can use the DATEPART function to return the specified part of a given date.* You can use the DATEVALUE function to return the date given a string representation of a date.* You can use the FORMAT function to return a text string of a number or date in a particular format.* The equivalent .NET function is Microsoft.VisualBasic.DateAndTime.DateSerial* For the Microsoft documentation refer to learn.microsoft.com
