INTDATECDC_NP (V008A_NP) is a 5-digit numeric variable.

## Description

INTDATECDC_NP (V008A_NP) reports century day code for the date on which the interview took place, according to Vikram Samvat, the official calendar of Nepal. This variable is only available for Nepali samples.

Century day codes (CDC) are particularly useful for checking the consistency of dates, calculating intervals between events, and imputing dates when the information for an event is missing or partially complete. They are similar to century month codes (CMC), but century day codes provide additional detail.

According to the DHS Program,

Users should note that while INTDATECDC_NP is calculated the same way as INTDATECDC, with the number of days since 1900, INTDATECDC_NP uses the number of days since 1900 in Vikram Samvat. This corresponds to April 14, 1843 in the Gregorian calendar.

For more information about the calculation of century month codes, see INTDATECMC (V008).

## Comparability

INTDATECDC_NP (V008A_NP) has no comparability problems.

All standard date variables in Nepal DHS samples are given in the Nepali calendar. The Nepali calendar, or Vikram Samvat, is a lunar calendar consisting of 12 months of 29 to 32 days each. According to the Gregorian calendar, the Nepali calendar begins in mid-April. Because the 12 months do not match the sidereal year, correctional months are occasionally added or subtracted. It is only possible to convert dates given in Vikram Samvat to the Gregorian calendar when the exact date (day, month and year) is available. Otherwise, it is only possible to approximate to the month. Vikram Samvat is approximately 56 years, 8 months, and 15 days ahead of the Gregorian calendar.
