Calculate Date

This activity allows you to take a Date Time and add or substract seconds from it. For example, you could take the current time, add 86400 seconds to it, and you’d have the same time tomorrow.


This activity expects two inputs. The first is a Date Time to use as the basis for adjustments. As in, this is the date that will be added to or subtracted from. You can provide this date as a string (in a supported format) or from a Date Time variable.

The second input is the adjustment to make to the original date, measured in seconds. By default, the number of seconds provided will be added to the date. If you provide a negative number of seconds, such as -86400, the adjustment will be subtracted instead. The activity’s output will be the new Date Time.


  • When using the variable browser to use this activity’s output, be careful which variable you select. Every activity has a Start time and End time which represent when the activity itself started and stopped running. The output from the activity is actually in the Result variable.
