I love crowdsourcing. Anyway, I'm playing with my budget spreadsheet* on Google Spreadsheet. I want to be able to highlight every second Friday as payday. But the conditional formatting doesn't appear to be set up for that/I don't understand how to do it with the conditional formatting rules available. Who has experience with Google Docs and knows how to do this? My last resort is to manually go through and highlight every second Friday, but please don't make me do that.

*If it exists I feel better about promptly ignoring it
