I do three things for current parents:
- I give out an annual printed calendar each September (as we follow the local school district calendar).
- I include special days & holiday school closures for the month on the monthly newsletter that is given out printed at the start of each month. (Ideally they put this one page newsletter on their refrigerator/cork board. I also have the same newsletter as the cover of the sign in binder each day.)
- I have a private class shutterfly site and add all holidays and special days in that calendar which is set to auto remind them of things on the calendar in advance. (Most parents opt-in for notifications from the site since I do not send many and they love seeing pictures of their kids on there.)
In addition to those three I may casually ask what they are doing on the holiday weekend (if time allows at pick up) and it is always listed on my website under the calendar section but currently enrolled parents never check my website only prospective clients/parents.
