Mohamadine,

(Apologies for replying in English - my French is pretty rusty...). The
reason for the small discrepances you have noticed is:

The DHIS2 is not using a monthly "annualisation" factor of 12 - it uses the
number of days in each month and in the year

So for instance for sep-17, the 115.2% you see are the result of something
like this:
    3985*(365/30)/221781 =  0.218613
+  17013*(365/30)/221781 =  0.933314847
=   1.151928 => 115.2%

If you change your Excel calc formula to using the days per month/year
approach, it would be 20998*(365/30)/221781 = 1.1492 => 115.2%

So for Jan/Mar/May/Jul/Aug/Oct/Dec you would use 31 days, for Feb 28 days,
and 30 days for the other months.

Best regards from a winterly Cape Town
Calle
