Diary is a way to record personal life and feelings, usually in written form. The following are the common diary formats I have compiled:

Date: Write down the date. I usually write the year, month and day, or I can just write the month and day.

Weather: Write down the weather conditions at that time, such as sunny, cloudy and rainy days.

Mood: Write down your mood, such as happy, sad, angry and calm.

Events: I usually write down the important events that happened that day.

Feelings: I will also write down my feelings and thoughts about what happened that day.
