Converting date to week number over several years
Hi,
I understand how to use the weeknum() function to conert a date to a week number, but this is only useful if need to convert 1 year. What should I do to convert 4 consecutive years to a week number, so all weeks numbers are not the same. e.g I want to make January 1st 2006 as week '1' and January 1st 2007 '53' instead of 1 again. Thanks very much. |
