Codes and Frequencies
TETNUS4YR_NP reports the year (according to Vikram Samvat, the official calendar in Nepal) that the respondent received her fourth tetanus toxoid immunization. TETNUS4YR_NP is only available for the Nepali samples.
The complementary variables TETNUS4DAY_NP and TETNUS4MO_NP report the day of the month and the month of the respondent's fourth tetanus toxoid immunization, according to Vikram Samvat, as recorded on a vaccination card shown to the interviewer.
TETNUS4YR_NP has no comparability problems across the Nepali samples.
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.
Comparability - Standard DHS
TETNUS4YR_NP is a country-specific variable, and it is not included in any phase of the standard DHS questionnaire.
