I’m trying to do this… def validate ``` errors.add_to_base "requested start date must be a monday" if ``` requested\_start\_date != Chronic.parse(‘monday’) end Not working though - this fails vaildation all the time (regardless of whether the date is a monday or not) What am I missing here ? thanks bb ---

As a result your code doesn’t check that the day of week is monday, it checks whether it is a particular monday at a particular time. You should look at the wday method on Time/Date, which returns the day of week. Fred ---

I have Chronic in place - can it help me work out if the date is a Monday? ---

YOU GOT IT :-)… Thanks Fred (again)… easy, no need for chronic… this seems to work ``` errors.add_to_base "requested start date must be a monday" if ``` requested\_start\_date.wday != 1 1 being Monday bb.
