日記通常用一般過去時敘述，英文日記格式和中文日記稍有區別。中文日記格式先寫日期，再寫星期幾，最後寫天氣。英文日記格式則先寫星期，再寫日期，對於天氣，英語國家人士已經很少寫. 星期和日期寫在左上角，天氣寫在右上角
日期格式用月日年（美式）或日月年（英式）都可以
1. 年、月、日都寫時，通常以月、日、年為順序，月份可以縮寫，日和年用逗號隔開。例如：december 18, xx或者dec. 18, xx。
2. 如果要寫星期，星期要緊挨日期，它既可以放在日期前面，也可以放在日期後面，星期也可以省略不寫。星期和日期之間不用標點，但要空一格，星期也可縮寫。例如：thursday dec. 18, xx或dec.18，xx thursday
3. 天氣情況必不可少。天氣一般用一個形容詞如:sunny, fine, rainy, snowy等表示。天氣通常位於日記的右上角。
下面是一篇關於英語日記範文。
january 18, xx friday sunny
i am free now as i am spending my winter holiday.
although we have some homework, we can finish them in several days. and the rest time we can make good use of. my god! we have been very tired after hard studying. in winter holidays, i want to have full sleep and eat good food in order to replenish myself. last but not the least, i will have a good rest.
i have rested for a week. i began to feel bored. so i went out with my friends. they are my best friends in the middle school. we didn’t go to someplace special. we just saw the other. we had lunch together. while we were having lunch, we were still talking about the new school and new friends. yes! a year later, we have grown riper. and we learned much more things and got new life. we haven’t enough time to play, to waste and to lose the way. we only have two years. two years to go, we will get the real life which belongs to us.
