Description
The aqDateTime.AddMonths method adds or subtracts the specified number of months to (from) the specified Date/Time value and returns the resultant date/time.
Declaration
aqDateTime.AddMonths(InputDate, Months)
| InputDate | [in] | Required | Date/Time | |
| Months | [in] | Optional | Integer | Default value: 1 |
| Result | Date/Time | |||
Applies To
The method is applied to the following object:
Parameters
The method has the following parameters:
InputDate
Specifies the original date and time.
Months
Specifies the number of months to change. If Months is positive, then the given number is added. If Months is negative, then the given number is subtracted.
Result Value
The value of the Date/Time type that is earlier or later than InputDate by the number of months specified.
Remarks
If an invalid date is generated upon adding or subtracting a month, the last day of the resulting month is returned. For example:
January 31st + 1 month = February 31st (not a valid day) = February 29th (leap year) or February 28th (non-leap year)
May 31st - 1 month = April 31st (not a valid day) = April 30th
Example
The code below demonstrates how you can change a date and/or time by adding some values to it.
JavaScript, JScript
function ChangingTime()

var Time1, Time2, Time3, Time4, Time5, Time6, Time7;
Time1 = aqDateTime.Now();

Time3 = aqDateTime.AddHours(Time1, 7);
Time4 = aqDateTime.AddMinutes(Time1, 24);
Time5 = aqDateTime.AddMonths(Time1, 2);
Time6 = aqDateTime.AddSeconds(Time1, 15);
Time7 = aqDateTime.AddTime(Time1, 9, 3, 24, 51);
