Play around with this example:
Code:
#!/bin/ksh

# Works only with GNU date

d1="Tue Nov 02 22:00:00 EDT 2010"
d2="Fri Nov 05 22:00:00 EDT 2010"
cdate=$(date)

dat1=$(date +%s -d "$d1")
dat2=$(date +%s -d "$d2")
curr=$(date +%s -d "$cdate")

if [ $curr -gt $dat1 -a $curr -lt $dat2 ]
then
  echo Current date is between "$d1" and "$d2"
fi
