I have a large spreadsheets with a list of events and 2 columns for dates.
The date that the even was originally scheduled for and the date that it
actually happened.
The events go into next year and just realized that starting Jan 1, 2009 the
dates are erronously listed in the format 01/01/08 as 2008. So I need to
update all the dates from Jan forward to read XX/XX/09, how can I do this
without affecting the 2008 dates.
