    Hello, paul2311!

    I see no need for the "if".


    I would be grateful if you could help me put this formula into simple words

    . . . \begin{array}{c}x \le y\text{ and }1/08/2010 \le y \le 31/07/2011\\ \text{or} \\ x > y\text{ and }1/08/2010 \le x \le 31/07/2011 \end{array}

    \begin{array}{c}x\text{ precedes or equals }y \\\text{and}\\ y\text{ is among the dates} \\ \text{Aug. 1, 2010 to July 31, 2011} \\ \\ \text{or} \\ \\ x\text{ succeeds }y\\ \text{and} \\ x\text{ is among the dates} \\ \text{Aug. 1, 2010 to July 31, 2011}   \end{array}

    Re: Help with formula

    Thank you for a prompt explanation Soroban. Could I in this instance read it as follows?

    X proceeds or equals y and y between Aug 1 2010 and July 2011
    Or
    X succeeds y and x between Aug 1 2010 and July 2011

    Thank you

    I would be careful with the word "between".
    Some may assume that it means literally between,
    . . not including the end dates.
