Organization

Hello to all mommy I need some help. Both me and my husband work full time, I'm also going to college part time. my job is alot more flexible than his so I run the errands, pay the bill's and take the kids to appointments but with everything going on I'm starting to forget appointments, important meetings, everything. I've tried to add them to my phone calendar but it wont remind me to the day of. How do you guys keep on track and not forget important events, meetings, appointments, ect?
