Hi Raheel,

Part of the challenge here is that these EpiWeeks are not standardized.
They thus become impossible to reliably calculate the weeks
determinstically, which is usually needed with DHIS2 (the Nepali calendar
being an exception).  Ideally we would have a means to implement whatever
type of intervals which are needed, but at the moment, all period types in
DHIS2 are "hardwired", so adding a new type (e.g.EpiWeeks) could be done,
but in this case, it may not be so simple.  For instance, look carefully
here (
http://www.cmmcp.org/2008EPI.htm) and here (
http://www.cmmcp.org/2009EPI.htm).  Note that one week is simply missing
(Dec 28th 2008-Jan 3 2009) but there are no clear rules about how to number
this week.  The ISO week system handles this and is thus fully
deterministic.  So, not to say it could not be done, but without a fully
standardized and rigorous definition  of what an EpiWeek actually is, I
think and potential implementation could be problematic.

Regards,
Jason

Hi Jason,

I am referring to CDC Epi week which starts from Sunday and ends on
Saturday. Please refer to the Epi week calender link

Thanks and best regards,
Raheel
