how to calculate a future date

how to calculate a future date

how to calculate a future date

Good Morning

I have been trying to find a way to calculate a future date based upon an already existing date
being passed into a routine

My question is this

I have a date, for example 05/25/16 and I need to add 48 months plus 10 days to create this future date
basically for 10 business days, not a full days tens

I also have to check for holiday's after the future has been created

I can do this in Visual Foxpro, but where I am they are going to .net and this would be a great subroutine
for future processing

So if anyone can point me in the right direction on this greatly appreciated

Thanks in advance

RE: how to calculate a future date

Use the DateAdd function.

Dim CurrentDate AsDate

Dim NewDate As Date

NewDate = DateAdd(DateInterval.Month, 48, CurrentDate) 'add 48 months

Select Case NewDate.DayOfWeek
Case DayOfWeek.Saturday
NewDate = DateAdd(DateInterval.Day, 13, NewDate) 'Add 13 days: 1 to get to Sunday, 5 for the first week, 2 for the weekend, 5 more for the next week (10 business days)
Case DayOfWeek.Sunday
NewDate = DateAdd(DateInterval.Day, 12, NewDate) 'Add 12 days: 5 for the first week, 2 for the weekend, 5 more for the next week
Case Else
NewDate = DateAdd(DateInterval.Day, 14, NewDate) 'Add 14 days: 10 business days and 4 for weekends

End Select

RE: how to calculate a future date

What you really need is a business-day calendar table. Every manufacturing company I've worked for has had a manufacturing-day calendar, that you can join to your table(s) and simply add to the business-days to arrive at a valid work day. No guessing for holidays or other non-work days.
