Like this?
awk -F, '{$0=$0"/"$4;for(i=1;i<=$4;i++) print}' file

I hope the headers are just to differentiate the fields and do not actually occur in the input.

awk -F, 'BEGIN{split("Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec",mname,",")
for(i=1;i<=12;i++) mnum[mname[i]]=i}
 $3=mname[mon++] sprintf("%02d",yr)
 if(mon==13) {yr++;mon=1}
}}' OFS=, file
