There are a couple of holidays that fall on specific days and not specific dates. For example, Thanksgiving falls on the last Thursday of November. It doesn't have an exact date for the holiday like Christmas or Halloween. But, that isn't stopping Snickers. Snickers is disappointed that Halloween falls on a Thursday this year so they are proposing that we move the date of Halloween to the last Saturday of October.
They recently said in a tweet that they'd be willing to give out a million free candy bars if we could change when Halloween is. I mean, I'm down. Who likes celebrating Halloween on a weekday anyway?
