Calculating elapsed time is very common whether you are managing a project or raising a baby. Elapsed time is nothing but interval between a starting point and the current point in time. We can use excel formulas to calculate elapsed time very easily.
Calculating elapsed time in years
For all the examples in this post we assume the starting date and time from which we need to calculate elapsed time is in Cell A1.
To calculate the elapsed time in years, use the formula =(NOW()-A1)/365 [Help on NOW formula]
Elapsed time in months
To calculate the elapsed time in months, we can use the formula =(NOW()-A1)/30. This returns the value in 30 day months.
Elapsed time in weeks
To calculate the elapsed time in weeks, we use the formula =(NOW()-A1)/7
Elapsed time in days
To calculate elapsed time in days, the formula is simple =TODAY()-A1. [Help on TODAY formula]
The result includes fractions as well. You can use number formatting to remove the values after decimal point.
Elapsed time in working days
To calculate elapsed time in working days, we can use the NETWORKDAYS formula like this = NETWORKDAYS(A1, TODAY()). This formula assumes 5 working days per week starting with Monday. You can also add an optional list of holidays as a parameter to it.
But if your working week is not from Monday to Friday, you can try the NETWORKINGDAYS() UDF in the same way.
Elapsed time in hours
To calculate elapsed time in hours, we can use the formula =(NOW()-A1)*24
Elapsed time in minutes
To find out elapsed time in minutes, use the formula =(NOW()-A1)*24*60
Elapsed time in seconds
In some machine critical scenarios, you might want to find the elapsed time in seconds. Just use the formula =(NOW()-A1)*24*3600

6 Responses to “Make VBA String Comparisons Case In-sensitive [Quick Tip]”
Another way to test if Target.Value equal a string constant without regard to letter casing is to use the StrCmp function...
If StrComp("yes", Target.Value, vbTextCompare) = 0 Then
' Do something
End If
That's a cool way to compare. i just converted my values to strings and used the above code to compare. worked nicely
Thanks!
In case that option just needs to be used for a single comparison, you could use
If InStr(1, "yes", Target.Value, vbTextCompare) Then
'do something
End If
as well.
Nice tip, thanks! I never even thought to think there might be an easier way.
Regarding Chronology of VB in general, the Option Compare pragma appears at the very beginning of VB, way before classes and objects arrive (with VB6 - around 2000).
Today StrComp() and InStr() function offers a more local way to compare, fully object, thus more consistent with object programming (even if VB is still interpreted).
My only question here is : "what if you want to binary compare locally with re-entering functions or concurrency (with events) ?". This will lead to a real nightmare and probably a big nasty mess to debug.
By the way, congrats for you Millions/month visits 🙂
This is nice article.
I used these examples to help my understanding. Even Instr is similar to Find but it can be case sensitive and also case insensitive.
Hope the examples below help.
Public Sub CaseSensitive2()
If InStr(1, "Look in this string", "look", vbBinaryCompare) = 0 Then
MsgBox "woops, no match"
Else
MsgBox "at least one match"
End If
End Sub
Public Sub CaseSensitive()
If InStr("Look in this string", "look") = 0 Then
MsgBox "woops, no match"
Else
MsgBox "at least one match"
End If
End Sub
Public Sub NotCaseSensitive()
'doing alot of case insensitive searching and whatnot, you can put Option Compare Text
If InStr(1, "Look in this string", "look", vbTextCompare) = 0 Then
MsgBox "woops, no match"
Else
MsgBox "at least one match"
End If
End Sub
