As Mom has gotten more frail, I realized I can't rely on her anymore to remind me about birthdays, and she couldn't remember years at all (neither could I.) So I typed out a list of birthdays and anniversaries for all of our surviving family members. I called and emailed everyone whose dates I didn't have, then mailed and emailed the list to everyone. So now there won't be a need to wonder when this one was born or how old that grandchild is. And it won't be crucial to transfer dates to the calendar.
