I'd like to create a macro in the Visbility of a webpart to set the visibility if the Month # is 1-4. Simple logic in C# would be:

if (Now.Month >= 1 && Now.Month <=4)
{
    // do my work
}

How do I get that similar syntax in a macro without creating a custom macro?

I know I can get the month pretty easy {% Now.Month %} but how do they all work together or how can I perform those comparison operations?
