A Business calender for Scheduling IT maintenance

[SUHEL AKTHER Md]

hi @all
can anyone help me to solve this below scenario

*A business calendar should be configured for scheduling IT maintenance activities. The calendar should take into account working hours and holidays, ensuring that maintenance activities are scheduled during non-peak times.

Hi @SUHEL AKTHER Md ,

Define a Business Calendar

• Navigate to Business Calendars (Business Calendar [cmn_schedule]).

• Create a new calendar that matches your IT team's working hours (e.g., weekdays 9 AM–6 PM).

• Use the "Add Exception" option to register holidays or other non-working days where no changes or maintenance should happen.

This calendar will essentially tell ServiceNow when the business is active — which you can use to figure out non-peak hours.

2: Create a Maintenance Schedule

• Create another schedule that represents your preferred maintenance windows — for example, evenings 10 PM–2 AM, weekends, or other non-peak times.

• Again, add exceptions if there are known blackout periods (big launches, quarter close, etc.).

This schedule acts as the “allowed window” for maintenance activities.

3: Use these schedules in your process

Depending on your process, you can:

• Use the Change Request window fields (Planned start / Planned end) with a client script or UI policy that checks if the selected time falls inside your maintenance window.

• Configure Change Blackout Schedules (Change > Blackout Schedules) to explicitly block changes from being scheduled during peak hours or critical periods.

 4: Automate validation

• Use a Business Rule or Scripted Validation to check:

  • If the planned time is inside your approved maintenance window.

  • If it overlaps with business working hours (and warn the requester).
