[igbert]

Is there a fuction to return the days in a given year?

Entry Return

assume 2008 is in a2
in b2
=DATE(A2+1,1,0)-DATE(A2,1,0)

Success - click yes.

 

[Dave Peterson]

=date(2010,1,1)-date(2009,1,1)
would give the number of days in 2009.

If you put the interested year in A1, you could use:
=date(a1+1,1,1)-date(a1,1,1)

(well, except for 1900.)

 

[Ms-Exl-Learner]

Assume that you are having the Year in A1. Copy and paste the below formula
in B1 cell.
=IF(A1="","",DATEDIF(DATE(A1,1,1),DATE(A1+1,1,1),"D"))

Remember to Click Yes, if this post helps!

 

[igbert]

Thanks, formula works preferct for any year.

assume 2008 is in a2
in b2
=DATE(A2+1,1,0)-DATE(A2,1,0)

Success - click yes.

 

[Brad]

You're welcome

Another approach that would also work

=365+(MONTH(DATE(A2,2,29))=2)

Success click yes

Micky,

I like the second formula, very neat, but I'm afraid the first gives errors,
you would need to do this to get the correct result using MOD

=IF(OR(MOD(A1,400)=0,AND(MOD(A1,4)=0,MOD(A1,100)<>0)),366, 365)

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.

You're welcome

Another approach that would also work

=365+(MONTH(DATE(A2,2,29))=2)

Success click yes

=337+DAY(DATE(A1,3,0))

Regards,

Mickey,

Would you be so kind and check your suggested formula for the years:
1908, 2008, 2108 and 2200(!)

Of course


1908 = leap year
2008 = leap year
2108 - leap year
2200 - Not a leap year

Mickey,

For clarification:-

A leap year is every 4 years, but not every 100 years, then again every 400
years

Micky,

If you recognize the following formula as the one suggested by you - check it

No I don't recognize that formula! I posted :-
=IF(OR(MOD(A1,400)=0,AND(MOD(A1,4)=0,MOD(A1,100)<>0)),366, 365)

You posted:-
=IF(OR(MOD(A1,400)=0,AND(MOD(A1,4)=0,MOD(A9,100)<>0)),366, 365)

Note the error in your formula referring to A1 & A9 and in the one in the
image you posted (A7 & A14) and hence the erronious results you are getting.

My formula returns 366 for 1908, 2008 & 2108 & 365 for year 2200 which isn't
a leap year by the following definition:-

A year will be a leap year if it is divisible by 4 but not by 100. If a year
is divisible by 4 and by 100, it is not a leap year unless it is also
divisible by 400.

Micky.

I'm glad we resolved that.
