Hello @Naresh E and welcome to Microsoft Q&A.
As far as I can tell, that looks correct, I think.
At this time I am not ware of any "predictive calendar" feature in ADF, but you are not the first to ask about it, I think it would be a wonderful addition, as I agree the triggers can be somewhat confusing. Please upvote in the feature forum. The more demand is visible, the more likely it will be implemented.
I would recommend creating another trigger for testing, similar in structure, but aimed for a much closer date in the future.
