Non tech: Simple method to delete all contacts birthdates

[zalpus]

When my company imported contact and account details into Sugar, somehow the birthday field became populated with dates. This in turn complicated syncing with outlook and Blackberry etc. over time with partial fixes.
Question: is there some straightforward way to delete all birthday field information, or is it simpler to do it manually for a non technical/coder, end user?
Thanks, Tony

The only simple method is to run a sql statement

update contacts set birthdate=null;

in the database query browser.
