Syntax
DateSerial(year, month, day)
The DateSerial function syntax has these arguments:
Part | Description |
year | Number between 100 and 9999, inclusive, or a numeric expression. |
month | Any numeric expression. |
day | Any numeric expression. |
Remarks
To specify a date, such as December 31, 1991, the range of numbers for each
DateSerial argument should be in the normally accepted range for the unit; that
is, 1–31 for days and 1–12 for months. However, you can also 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.
The following example uses numeric expressions instead of absolute date numbers.
Here the DateSerial function returns a date that is the day before the first
day (1 - 1) of two months before August (8 - 2) of 10 years before 1990 (1990
- 10); in other words, May 31, 1980.
DateSerial(1990 - 10, 8 - 2, 1 - 1)
For the year argument,
values between 0 and 99, inclusive, are interpreted as the years 1900–1999.
For all other year arguments, use a complete four-digit year (for example, 1800).
When any argument exceeds the normally accepted range for that argument, it
increments to the next larger unit as appropriate. For example, if you specify
35 days, it is evaluated as one month and some number of days, depending on
where in the year it is applied. However, if any single argument is outside
the range -32,768 to 32,767, or if the date specified by the three arguments,
either directly or by expression, falls outside the acceptable range of dates,
an error occurs.
