[Boost-users] [date time] are months and years derived from date_duration?

Hi I have simple problem if months and years derived from date_duration? The goal is that user can dynamically choose a time of events that appear periodically in shedule e.g. every 20th of any month is a meeting or every 3 months something other happens or birthsday is one per year.
