Many time while coding we come across the requirement in which we need to calculate the EndDate from a StartDate after a specific number of business/working days. That means excluding the weekends (Saturday & Sunday) Following is the code snippet which does this. I know there can be an optimized way of doing this. But I didn’t want to spend more time on this.
Below method takes date and number of working days to be added to the date.
Method daysOff calculates the number of non-working days coming in the start date and end date. And after which we are again adding those number of days.
