Learn how to use the abs function in Notion formulas.
The abs() function calculates the absolute value of a number.
1
abs(number)
A number’s absolute value is simply how far it is away from zero. Therefore, the absolute value of a negative number is equal to its positive equivalent - e.g. abs(-5) == 5.
In mathematical notation, absolute values are expressed by wrapping a number in || signs:
$|-12\;| = 12$

## Example Formulas

1
abs(-42) // Output: 42
2
3
abs(42) // Output: 42

Notion’s dateBetween function subtracts the second argument from the first, and returns a number depending on the specified unit of time (e.g. “hours” or “seconds”).
If the second argument is a later date than the first argument’s date, dateBetween() will return a negative number. The formula in the table below uses the abs() function to ensure that the output is always positive.

### “Seconds Between” Property Formula

abs(dateBetween(prop("Date 1"), prop("Date 2"), "seconds"))
