日記是把自己在當天生活中經歷的有意義的事以及見聞感受記錄下來的書面形式。文體自由，不拘一格。通常用第一人稱記寫。
英語日記的格式與漢語相同。在正文上方自左起頂格寫上日期、星期幾和天氣情況。正文另起一行，內容應有所選擇，記有意義、感受最深的事，切忌流水賬。有話則長，無話則短，甚至三言兩語亦可。通常採用一般過去時或可靈活運用。日記的寫作格式如下：
1）
sept 23, 1991, wednesday cloudy
it is three months since i began this diary…
2）
friday, may i fine
today is may day…
月份除may, june, july外，其餘可用縮寫形式。常用來表示天氣的詞有fine, cloudy, rainy, windy, snow等。
【範例】
oct 3, 1999, sundayrainy
it was raining outside when i got up early in the morning. it's too bad, i had to go to school by bus. i said to myself. it was almost seven o'clock before i left home. i put on my raincoat and ran to the bus stop in a hurry, for i thought a lot of people might be waiting there. hardly had i got there when a bus was coming. i got on the bus immediately, hoping it was possible for me to take a seat. i saw an empty seat and took it. but i found an old lady standing behind me. i stood up at once and was about to ask her to take the seat when a young girl in a modern skirt made a dive for it. i could hardly believe it. i glared at her, thinking“what bad manners! she cares for nobody but herself. won't she grow old in the future?”
