Module Dates

Hi Folks,

I’ve created a module showing an iFrame, so far so good. The URL to the external website take parameters from date fields. I can set one of the fields to today - which is what I need, but I can’t set the default date of the other to the start of the month…

Start Date = 1st of the month (set dynamically according to whatever month it is currently)
End Date = Today

Can someone give me directions on how to do this by any chance? I’m not familiar with MySQL, PHP, or Apache, which is the configuration I’m using on a Windows Server 2012 OS.

Thanks all - and apologies if this has been asked before (a search hasn’t turned up anything)
