[xwiki-users] AGE and calculating date

Hi, I think this might a velocity/java script or groovy question more as a xwiki question. We want to record a age (Period of days/seconds since birth date). What datatype would you recommend: - String structured - Numeric integer of Days or Seconds - Date/Time We would like to be able to display the data as: - Date notation - Years, Months, Weeks - Years, Months, Days - Years, Months Things to consider is that each month has different period lengths in days and that each 4 years we have different number of days in a year Should/Can we do this server side (velocity) What velocity tools or services can we use Gerritjan Koekkoek Vader van Rai Koekkoek (cdls) en voorzitter vereniging CdLS Visit our website<http://www.cdlsworld.org> Facebook<https://www.facebook.com/gerritjan.koekkoek> email&lt;gerritjan(a)cdlsworld.org&gt;
