Have you ever bought a diary and calendar for the same year for yourself?

Yes..................................

No, I've never had a diary.

Yes, many times! Nearly every year. In my diary, I write down all the details of certain things/events, and certain things I need to do. Yet, my calendar is only used for me to keep track of my work shifts and the deadlines of my uni assignments (so I can see how long I have to complete an assignment).
