Formula referencing time ranges

[RLCornish]

I need to create a formula influenced by arrival and departure times. Each individual will come and go at their allotted times. We are working within windows of time. For example, people coming between 8 a.m. and noon and departing between 11 a.m. and 3 p.m. will be on a specific schedule. There are 3 potential windows for arrivals and departures, so 9 potential schedules. The matrix is below. My end game is to populate what schedule an individual is on based on their arrival and departure being between specific ranges. The function will translate to better than 300 individuals so you can imagine we do not want to have to manually figure out which schedule for each person.

I've fiddled with IF's and can get it to work for a single line of the below matrix, and could probably nest all of it, but it would be ugly. I feel like INDEX/MATCH should be a good option, but cannot figure out how to make the "matches" work because of the time ranges. I'm stumped and would very much appreciate some help.


Below this table are the attendees actual arrival and departure times...

It makes perfect sense, but I would not have gotten there. Huge thanks!

Alternatively, you can create a function through VBA & use it in your worksheet directly as =FindSchedule( select arrival time cell, select departure time cell )

Function FindSchedule(Arrival As Date, Departure As Date) As String

Application.Volatile

    If (Arrival >= #8:00:00 AM# And Arrival <= #12:00:00 PM#) And (Departure >= #11:00:00 AM# And Departure <= #3:00:00 PM#) Then
        FindSchedule = "A"
ElseIf (Arrival >= #12:01:00 PM# And Arrival <= #4:00:00 PM#) And (Departure >= #11:00:00 AM# And Departure <= #3:00:00 PM#) Then
        FindSchedule = "B"
ElseIf (Arrival >= #4:01:00 PM# And Arrival <= #10:00:00 PM#) And (Departure >= #11:00:00 AM# And Departure <= #3:00:00 PM#) Then
        FindSchedule = "C"
        
ElseIf (Arrival >= #8:00:00 AM# And Arrival <= #12:00:00 PM#) And (Departure >= #3:01:00 PM# And Departure <= #6:00:00 PM#) Then
        FindSchedule = "D"
ElseIf (Arrival >= #12:01:00 PM# And Arrival <= #4:00:00 PM#) And (Departure >= #3:01:00 PM# And Departure <= #6:00:00 PM#) Then
        FindSchedule = "E"
ElseIf (Arrival >= #4:01:00 PM# And Arrival <= #10:00:00 PM#) And (Departure >= #3:01:00 PM# And Departure <= #6:00:00 PM#) Then
        FindSchedule = "F"
        
ElseIf (Arrival >= #8:00:00 AM# And Arrival <= #12:00:00 PM#) And (Departure >= #6:01:00 PM# And Departure <= #9:00:00 PM#) Then
        FindSchedule = "G"
ElseIf (Arrival >= #12:01:00 PM# And Arrival <= #4:00:00 PM#) And (Departure >= #6:01:00 PM# And Departure <= #9:00:00 PM#) Then
        FindSchedule = "H"
ElseIf (Arrival >= #4:01:00 PM# And Arrival <= #10:00:00 PM#) And (Departure >= #6:01:00 PM# And Departure <= #9:00:00 PM#) Then
        FindSchedule = "I"
Else: FindSchedule = "Out of timing range"
End If

End Function

You're welcome.

That's an interesting piece of VBA code, mse330. I have another project I'm working on where this could be very helpful. Thank you for this.

 

[mse330]

That's great ! ... You are most welcome
