The issue for Nepal is that the local calendar years were used in the calculation of CMCs instead of the Gregorian calendar that is used in the west. For example, the current year in Nepal is 2069 and it started on April 13, 2012. The standard CMC calculation is done, but using the Nepali dates, so April 2012 (CMC 1348 if using the Gregorian calendar) is CMC 2029 based on the Nepali dates. You can convert the CMCs to the Gregorian calendar by subtracting the difference (681). This is approximate as the Nepali month starts in the middle of the Gregorian month, but should be good enough for most purposes. This should work for each of the surveys, except for the 1996 survey. For the 1996 survey the years were recorded using 2 digit years and the Nepali year 2052 was recorded as just 52. For this survey to convert to Gregorian dates, add 519 to the CMC.

As Kerry points out for most analysis the fact that the CMC is based on the local calendar years has no effect on the analysis unless you are interested in absolute dates.
