Agenda

Children buy agenda's that start at the beginning of the schoolyear.
Grown ups buy agenda's that start with: january 1.

It's far more convenient for moms of schoolkids to have an agenda that starts with the schoolyear too.

You can use a schoolagenda for even more comvenience, because you can write down schedules, and all sorts of other things which are important for moms of schoolkids.
