Or if you are using ksh93 then you can use builtin properties:
Code:
#!/bin/ksh93
((daysec=24*60*60))
dstr="$1"
y=${dstr:0:4}
m=${dstr:4:2}
d=${dstr:6:2}

day=$(printf "%(%#)T"   "$y-$m-$d+00:00:00")
((prev=day-daysec))
printf "%(%Y%m%d)T  \n" "#$prev"
# or this enough in this case, no need for time
day=$(printf "%(%#)T"   "$y-$m-$d")
((next=day+daysec))
printf "%(%Y%m%d)T  \n" "#$next"
