Calculate Business Days Duration action

[Soumyadeep10]

I have created an ServiceNow action which is described as follows:

Name: Calculate Business Days Duration

What it does :

1. This action takes Start date, end date and the chosen Business Schedule as input and calculates the true elapsed time between a start date/time and end date/time.
2. It uses a defined Business Schedule (like 8-5 weekdays) and ignores nights, weekends.
3. It gives the result as a string (eg: 2 day 12 hours).
4. It also carries a Start date and End date validation where if the Start date is after End date, it throws error!

Let's explain with an example:
Inputs -

• Start date: 9.10.25 21:00:00
• End date: 16.10.25 21:00:00
• Schedule: 8-5weekdays [which means 8:00AM to 5:00PM, Mon-Fri, 45 hours per week]

Output with explanation-
The total calendar time between the times chosen is exactly 7 days. The action ignores all times except the scheduled business hours.

• Oct 9 (Start): The start time is 9:00 pm which is outside the schedule so, the action waits for next day.
• Oct 10 (Friday): Counts 9 hours
• Oct 11-12(Weekend): Counts 0 hrs.
• Oct 13-17 (Mon-Fri): Counts 9 hours each day * 5 days = 45 hours.
• Total is 9 + 45 = 54 hours

Result = 2 day 6 hours

[Note: The result may vary based on different timezone settings on instance]

Hi @Soumyadeep10
Thank you for your contribution
Positive scenarios are working well, can you also add additional checks for

• 'If start date is after end date' then return a message
• Add conditions for 'Error Evaluation' if step1 fails.
• Add your logic in try/catch statements.
