Following is a response from DHS staff member, Tom Pullum:
A note to other forum users--the question is now about Zambia even though the subject line says "Philippines".
Without going into the file myself, I can speculate that there are two possible reasons for the difference. The first is that the number of stillbirths in the report will be weighted (by v005). If your number is unweighted, it will differ. A second reason is that the code I gave is for all months in the calendar, not just the 60 months before the month of interview. You can reduce vcal_1 to just the 60 months before the interview, and that will give a smaller number. You should be able to reduce vcal_1 to just the last 60 months, with the name "vcal", with this line: "gen vcal=substr(vcal_1,v018,60)".
I hope you can get close to a match if you reduce vcal_1 to vcal and count the weighted number of stillbirths, but there may still be some discrepancy because of pregnancies of indeterminate length at the beginning (the right end) of the calendar.
