Calculate Date Time Difference

This activity calculates the difference between two Date Times. It returns two sets of variables: one set represents the difference between the two dates and the other represents the total amount of time between the two in various units of time.


This activity expects two inputs. The first is the Original Datetime that we’ll subtract another date from. You can provide this date as a string (in a supported format) or from a Date Time variable.

The second input is the date to subtract from the original. You can provide Subtract Datetime as a string (in a supported format) or from a Date Time variable.


If Original Datetime is 2020-12-02T10:00:00Z and Subtract Datetime is 2020-12-01T10:00:00+00:00, we get the sample outputs below:

These variables represent the difference between the two datetimes. Note that these added together will equal the total amount of time between the two inputs:

Variable Name Sample Output
Days 1
Hours 0
Minutes 0
Seconds 0
Milliseconds 0

These variables each represent the total amount of time between the two inputs, but in different units of time:

Variable Name Sample Output
Total Days 1
Total Hours 24
Total Minutes 1440
Total Seconds 86400
Total Milliseconds 86400000

Supported Date Formats

The following date formats can be used as input into this activity. You can also use a Date Time variable.

UnixDate = 'Mon Jan 2 15:04:05 MST 2018'
RubyDate = 'Mon Jan 02 15:04:05 -0700 2018'
RFC822 = '02 Jan 18 15:04 MST'
RFC822Z = '02 Jan 18 15:04 -0700'
RFC850 = 'Monday, 02-Jan-18 15:04:05 MST'
RFC1123 = 'Mon, 02 Jan 2018 15:04:05 MST'
RFC1123Z = 'Mon, 02 Jan 2018 15:04:05 -0700'
RFC3339 = '2018-01-02T15:04:05-07:00'
RFC3339Nano = '2018-01-02T15:04:05.999999999-07:00'
Custom formats:
'02012018-150405 (Europe time format)'
Please notice that '01' always stands for Month and '02' stands for Day."
