I consider 7 days to be a week, so if I look at 1/1/2019 - 7/1/2019 I would say that is 7 days. But often I seen when people are calculating the number of days between 2 dates or age they use the formula B1-A1 where A1 is the Start Date/DoB and B1 is todays date/end date, this would give 6 for the above example.
I use (B1-A1)+1 which gives 7 and for dates of birth I would use ((B1-A1)+1)/365.25. Which is correct?

7 - 1 is 6, no? What is correct depends on your definition and whether you include timestamps or not. When subtracting 20190101T00:00:00 from 20190107T23:59:59, you get 6.999, which can be rounded appropriately.

The answer revolves around how Excel deals with dates. When days between dates are calculated using formulae such as B1-A1, Excel would turn the dates into serial numbers and use the serial numbers to calculate the number or days in between.
By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,447 days after January 1, 1900. (Source: Microsoft)
So the days between January 1, 1900 and January 7, 1900 would equal 7 minus 1 equalling 6.
The same would apply with 1/1/2008 - 7/1/2008
January 1, 2008 is 39,447 and
January 7, 2008 is 39,453
39,453 — 39,447 = 6
If you wish to count the days inclusive you would need to add 1 to make the formula to be for example B1-A1+1.
If you want to calculate days exclusive you would need to minus 1 day making B1-A1-1

It is not a question of one formula being right and the other being wrong. It is a question of what you are looking for.
Say you are working on a task 24 hours a day. You begin the task 17 January 2000 at 9:00 AM and complete the task 18 January 2000 at 9:00 AM. If the question is How many days did the task take ? You would take the difference; get 24 hours and answer 1 day.
If, however, the question is On how many days did you work on the task ? You would immediately respond 2
Thus =B1 - A1 or =B1 - A1 + 1 might be appropriate depending on what you are trying to measure.

I wold like to suggest 3 different Formula to Calculate AGE between 2 Dates.
- To get only Years:
=INT((B1-A1)/365)
Or,
=ROUNDDOWN(YEARFRAC(A1, B1, 1), 0)
Or, you may use TODAY() Function also:
=ROUNDDOWN(YEARFRAC(A1, TODAY(), 1), 0)
To Get Complete Age in Years, Months and Days use this one.
=DATEDIF(A1,B1,"Y") & " Years, " & DATEDIF(A1,B1,"YM") & " Months, " & DATEDIF(A1,B1,"MD") & " Days"
Edited:
Counting number of days between two Dates is little bit arbitrary. Basically depends on need.
- Count number of days, Excluding Start
Date. - Count number of days, Including Start
Date. - Count number of days, Excluding both
Start & End Date.
Considering OP's Sample Dates following Formula can be used.
Formula for situation 1:
=DATEDIF(B2,B3,"d")
=DAYS(B3,B2)
=INT(B3-B2)
Formula for situation 2:
=DATEDIF(B2,B3,"d")+1
=DAYS(B3,B2)+1
=INT(B3-B2+1)
Formula for situation 3:
=DATEDIF(B2,B3,"d")-1
=DAYS(B3,B2)-1
=INT(B3-B2-1)
Adjust Cell references in the Formula as needed.

This is over complicating things and doesn't answer the question (how many days). The OP is not asking number of years or years, months and days.

@ChrisRogers,, Read my post I've suggested all possible Formula, including the OP's one, regarding((B1-A1)+1)/365.25.It's really unfortunate to get DOWN VOTE after All !!

@ChrisRogers,, this is part of OP,,But often I seen when people are calculating the number of days between 2 dates or age they use the formula B1-A1

@ChrisRogers,, considering the Formula OP has written and I've shown in comments ,, my solution has Focused on ALL that and the Suggested one is an improvise version I've shown with my Answer !!=INT((B1-A1)/365)

INT((B1-A1)/365)can provide the wrong result if there is are leap years involved.

I wold like to suggest 3 different Formula to Calculate AGE between 2 Dates.
- To get only Years:
=INT((B1-A1)/365)
Or,
=ROUNDDOWN(YEARFRAC(A1, B1, 1), 0)
Or, you may use TODAY() Function also:
=ROUNDDOWN(YEARFRAC(A1, TODAY(), 1), 0)
To Get Complete Age in Years, Months and Days use this one.
=DATEDIF(A1,B1,"Y") & " Years, " & DATEDIF(A1,B1,"YM") & " Months, " & DATEDIF(A1,B1,"MD") & " Days"
Edited:
Counting number of days between two Dates is little bit arbitrary. Basically depends on need.
- Count number of days, Excluding Start
Date. - Count number of days, Including Start
Date. - Count number of days, Excluding both
Start & End Date.
Considering OP's Sample Dates following Formula can be used.
Formula for situation 1:
=DATEDIF(B2,B3,"d")
=DAYS(B3,B2)
=INT(B3-B2)
Formula for situation 2:
=DATEDIF(B2,B3,"d")+1
=DAYS(B3,B2)+1
=INT(B3-B2+1)
Formula for situation 3:
=DATEDIF(B2,B3,"d")-1
=DAYS(B3,B2)-1
=INT(B3-B2-1)
Adjust Cell references in the Formula as needed.

7 - 1 is 6, no? What is correct depends on your definition and whether you include timestamps or not. When subtracting 20190101T00:00:00 from 20190107T23:59:59, you get 6.999, which can be rounded appropriately.

@slhck That really makes sense when you think about the time as well as date.

If start date/dob and today are the same day, do you want the answer to be 0 or 1? B1-A1 is the number of complete days that have past.

You're asking whether exclusive or inclusive operations are correct. They're both correct, depending on what you are trying to achieve. See @Chris Rogers's answer below.
