You'll avoid party-schedule conflicts with your child's friends and enjoy great services like emailed planning reminders.   Why Be On Our Calendar? Your child's big day is coming up, the plans are going smoothly and then OH, NO! you find out you scheduled your party for the same day and time as another child who shares the same friends! Now instead of happy anticipation, your child feels utter dread wondering whose party will win out.   Don't let it happen to you – post your bar mitzvah party date and time on our calendar NOW and encourage everyone you know to do the same. You'll not only avoid disaster, but you'll get great benefits.
