Date Operators
An expression that uses a date operator returns a date or a number, depending on the operation. All date operations will result in an accurate date, taking into account the change between years and leap years. The following table shows the date operators:
| Operation | Syntax | Returns | Expression | Value |
| Date difference | Date – Date | Number | !1997-01-20! - !1997-01-01! | 19 |
| Day addition | Date + Number | Date | !1997-01-20! + 9 | !1997-01-29! |
| Day subtraction | Date – Number | Date | !1997-01-20! - 9 | !1997-01-11! |
