Hi,

Date.parse("28/03/2008") gives me an error?

I get:

ArgumentError: invalid date.

Any ideas how to fix this?

That would work, but so would this:

Date.strptime('28/03/2008', '%d/%m/%Y')

excellent thanks,
You'd think Ruby would provide some internationalisation type way of solving
this? (e.g. specifying your location/country or something). Guess not?

Hello,

Unfortunately for me, the solution by Ray doesn't seem to work too. For
instance I'm doing this..

dateStr = params[:startdate].to_s
logger.info "date - " + dateStr
startdate =Date.strptime(dateStr, '%m/%d/%Y').to_s

and though I get the string quite correctly as

date - 05/16/2008

I end up getting the ArgumentError - invalid date. Please let me know if
I am doing anything incorrect here.

Regards,
Shankar.

Doesn't look like it.
Date.strptime("05/16/2008", '%m/%d/%Y').to_s
works for me.

Does it have anything to do with the version of Ruby/Rails ? I'm using
Rails 1.1.6 and Ruby 1.8.4. Another wierd thing about this is
dateStr.to_time works while dateStr.to_date again gives me the same
exception.
