Blackout Date use for Change

[Steven Young]

So i've read a lot of threads about this blackout date.

I want to blackout all the upcoming holiday days and a day before and after.

I think it's something ServiceNow needs to go back to the drawing board and make a new option.

So   I want to Completely eliminate an entire day/week/month from the change process.

I dont want it based on a CI, i want it based on a date.

So for instance,   i want 0 changes done on 10/31.   i want to be able to select 10/31 and mark it as blackout for ALL CI's.  
I dont even want it to be an option to select from the start_date field.   I want the date 10/31 to be greyed out and not selectable.

Does anyone have a script and table or something that can make this work?

After researching the blackout calendar, it's not very functional since it's limited to 1 CI.

The Blackout Calendar should be directly related to the change process, so as soon as i update 1 date, it should show on the change calendar as blacked out.

i'm almost tempted to create a new table,   list my dates for blackout.

Do a onChange client script to look at the date selected and reference the table and give an immediate notification that this date is blacked out.

As you said, you can either create a custom table and do that or add schedules and check if the current date falls in any such schedules.. I don't think greying out the dates is possible ...

Do you know if it is possible to trigger a notification based on a selected date range as opposed to a blackout period?   I don't want to stop users from creating a change during a date range, I want to notify them of additional requirements during the specified dates.
