Posted on by AXBOY 607

Hi All,

I want to get the number of days from dateformula datatype, like 1M = 31D, 1Y = 365D, 1W = 7D  How can i achieve this ?

Also whats the difference between 28D and D28?

The result of : 

  1. CalcDate('-28D',Today()) = 2/29/2020. 
  2. ClacDate('-D28',Today()) = 2/28/2020 , how?   Please explain in detail?

    if the current date of your windows system is 3/28/2020 or e.g. 3/27/2020, then the result of CalcDate('-D28',Today()) is 2/28/2020. if the current windows date is later, e.g. 3/29/2020, then the result is 3/28/2020.

    Hi,

    You said, CalcDate('-D28',Today()) ; Output : 2/28/2020,

    But its giving : 3/28/2020, its returning the 28th of the current month not the previous month.

    Only for For X = 30 and 31, CalcDate('-DX',Today());  i am getting Output = 2/29/2020

    and for X =1-29,CalcDate('-DX',Today()); Output = 3/X/2020 ; It calcs the Xth day of the current month.

    Please Help!

    29/3/2020 is GB (english and global) notation

    3/29/2020 is US notation

    RE: How to get days from Date Formula datatype?

    I tried the following cases and the following results which doesnt quite really match what you said:

    Queries :

    Today() = 3/29/2020

    For X = 1 to 29, CalcDate('-DX',Today()); Output = 3/X/2020 ; It calcs the Xth day of the current month.

    For X = 30 & 31, CalcDate('-DX',Today()); Output = 2/29/2020

    For X = 1 to 30 ,  CalcDate('+DX',Today()); Output = 4/X/2020 ; It calcs the Xth day of the next month,which is correct like you said.

    But for X=  31, CalcDate('+DX',Today()); Output = 3/X/2020 ; It calcs the Xth day of the Current month

    PLEASE HELP!
