Calculating the difference in days between 2 date columns:
Inputs
One.
Options
•Set Column 1 to the first column you wish to operate on.
•Set Operation to the operation you wish to perform.
•Set Column 2 the second column you wish to operate on (binary operations only)
Notes
•The following operations are supported.
Operation |
Column 1 |
Column 2 |
Notes |
Examples |
|---|---|---|---|---|
+ Add |
Numerical addition |
1.2 + 3 = 4.2 |
||
Adds days to the date |
31/01/2021 + 7 = 07/02/2021 |
|||
- Subtract |
Numerical subtraction |
1.2 - 3 = -1.8 |
||
Subtracts days from the date |
31/01/2021 - 7 = 24/01/2021 |
|||
Days the date in Column 1 is after the date in Column 2 (negative if before) |
31/01/2021 - 24/01/2021 = 7 24/01/2021 - 31/01/2021 = -7 |
|||
* Multiply |
Numerical multiplication |
1.2 * 3 = 3.6 |
||
/ Divide |
Numerical division |
1.2 / 3 = 0.4 1 / 0 = Error |
||
^ Power |
Column 1 to the power Column 2 (col1col2) |
1.2 ^ 3 = 1.728 2 ^ -3 = 0.125 |
||
% Modulus |
Remainder after Column 1 is divided by Column 2 |
7 % 2 = 1 7 % 0 = Error |
||
Abs |
N/A |

|
Ceiling |
N/A |
The smallest integer that is not less than the value |
Ceiling( 1 ) = 1 Ceiling( 1.2 ) = 2 Ceiling( -1.2 ) = -1 |
|
DayOfWeek |
N/A |
Day of the week, where 1 = Monday and 7 = Sunday |
DayOfWeek( 31/01/2021 ) = 7 DayOfWeek( 01/02/2021 ) = 1 |
|
DayOfMonth |
N/A |

DayOfMonth( 31/01/2021 ) = 31 DayOfMonth( 01/02/2021 ) = 1 |
|
DayOfYear |
N/A |
Day of the year |
DayOfYear( 01/02/2021 ) = 32 DayOfYear( 31/12/2021 ) = 365 |
|
Decrement |
N/A |
Subtract 1 |
Decrement( 1 ) = 0 Decrement( -1 ) = -2 Decrement( 1.2 ) = 0.2 |
|
N/A |
Subtract 1 day |
Decrement( 31/01/2021 ) = 30/01/2021 |
||
Floor |
N/A |
The largest integer that is not greater than the value |
Floor( 1 ) = 1 Floor( 1.2 ) = 1 Floor( -1.2 ) = -2 |
|
Increment |
N/A |
Add 1 |
Increment( 1 ) = 2 Increment( -1 ) = 0 Increment( 1.2 ) = 2.2 |
|
N/A |
Add 1 day |
Increment( 31/01/2021 ) = 01/02/2021 |
||
Length |
Any |
N/A |
Then number of characters in the value (include any whitespace) |
Length( 1.2 ) = 3 Length( 31/01/2021 ) = 10 Length( abcd ) = 4 |
Ln |
N/A |
The natural (base e) logarithm of the value |
Ln ( 10 ) = 2.302 Ln ( 0 ) = Error |
|
Log10 |
N/A |
The common (base 10) logarithm of the value |
Log10 ( 10 ) = 1 Log10 ( 0 ) = Error |
|
Month |
N/A |
1 = January |
Month( 31/12/2021 ) = 12 |
|
Round |
N/A |
Round to the nearest integer |
Round( 1 ) = 1 Round( -1.2 ) = -1 Round( 1.5 ) = 2 |
|
Sign |
N/A |
1 if value > 0, 0 if value = 0, -1 of value < 0 |
Sign( 1.2 ) = 1 Sign( 0 ) = 0 Sign( -1.2 ) = -1 |
|
Year |
N/A |
The 4 digit year |
Year( 31/01/2021 ) = 2021 |
•Whether values are interpreted as number, dates or text depends on Supported date formats and Locale in the Preferences window.
•To concatenate text in different columns use the Concat Cols transform.
•To compare 2 columns use the Compare Cols transform.
•For logical operations use the If transform.
•For operations on rows or columns use the Stats transform.
•For more complex number/date calculations use the JavaScript transform.
•To modify the numerical precision of the results use the Num Format transform.
•To add a new column of values use the New Col transform.
