I am not getting the correct answer when using datetime function

Hi everyone,

I am using the following function

datetime(1,43100,1)

but instead of getting '31/12/2017' as an answer (as given from Excel), I am getting 01-Aug-3592. Apparently, I am missing something in the datetime function but don't know what it is.

Thanks in advance for your time.

>> datetime(43100,'ConvertFrom','excel')
ans = 
  datetime
   31-Dec-2017 00:00:00
>> 

You tried converting from (yr,mo,day) --> (1, 43100, 1) instead.

Thank you very much for the answer! How can I ignore the time part. I want to end up just with '31-Dec-2017' instead of '31-Dec-2017 00:00:00' .

The time part is always part of a datetime (hence the time in the name). You can avoid displaying it by changing the Format property:

>> datetime(43100,'ConvertFrom','excel', 'Format', 'dd-MM-yyyy')
ans = 
  datetime
   31-12-2017
>> datetime(43100,'ConvertFrom','excel', 'Format', 'eee dd MMM yyyy')
ans = 
  datetime
   Sun 31 Dec 2017

but note that the time part will still be taken into account for calculations (like date difference) whether or not it is displayed. Excel does the same.

You are using

t = datetime(Y,M,D)

Year = 1
month = 43100
day = 1

That is not what you intend I assume.

I think you want:

t = datetime(43100,'ConvertFrom','excel')
