Need to get some good points on preparing 2024 diary. What important contents it must have?

Greetings All, Just need to get some good points on preparing the 2024 diary. What important contents it must have? How could this be attractive and promising? Kindly share suggestions/PDF/PPT for this.
I need your help on an urgent basis.

You need to give members far more information about this.

We have no idea what you are talking about. What diary, who is the audience, what form the diary takes, your industry, you position, what it is for, etc etc.

Many of us are good, but we are not mind readers.
