英语作文日记格式如下：
Friday Feb.15th 2006 sunny
星期和日期写在左上角，天气写在右上角
日期格式用月日年(美式)或日月年(英式)都可以
1. 年、月、日都写时，通常以月、日、年为顺序，月份可以缩写，日和年用逗号隔开。例如：December 18, 2003或者Dec. 18, 2003。
2. 如果要写星期，星期要紧挨日期，它既可以放在日期前面，也可以放在日期后面，星期也可以省略不写。星期和日期之间不用标点，但要空一格，星期也可缩写。例如：Thursday Dec. 18, 2003或Dec.18，2003 Thursday
3. 天气情况必不可少。天气一般用一个形容词如:Sunny, Fine, Rainy, Snowy等表示。天气通常位于日记的右上角。
范文：
One Sunday my mother (Mother) had (made) me take my little young brother to the a trip to the country. She bade me take good care of him.
While we were walking along the road， the sun was shining brightly and the breeze was blowing gently. We saw the beautiful flowers smile (smiling) at us and heard the birds sing (singing) their sweet songs on the trees. The scenery was indeed very pretty (beautiful).
When we felt tired， we returned home. We saw Mother (our mother) wait (waiting) for us at the door.
有一个周日，我母亲叫我带小弟弟去乡村游历。她吩咐我要好好照料他。
当咱们沿着道路行走的时候，太阳灿烂地照耀着，微风轻轻地吹着。咱们看见美丽的花儿对咱们微笑着，并听见鸟儿在树上唱着悦耳的歌曲，风景实十分美丽。
当咱们感觉到疲倦的时候，咱们就回家了。咱们看见母样正在门口等候咱们。
英语作文日记格式与汉语日记的格式大致相同，在每篇日记的第一行写上日期、星期和天气，接下来写内容。
日期、星期和天气的书写要注意以下几个方面：
1. 年、月、日都写时，通常以月、日、年为顺序，月份可以缩写，日和年用逗号隔开。例如：December 18, 2003或者Dec. 18, 2003。
2. 如果要写星期，星期要紧挨日期，它既可以放在日期前面，也可以放在日期后面，星期也可以省略不写。星期和日期之间不用标点，但要空一格，星期也可缩写。例如：Thursday Dec. 18, 2003或Dec.18，2003 Thursday
3. 天气情况必不可少。天气一般用一个形容词如:Sunny, Fine, Rainy, Snowy等表示。天气通常位于日记的右上角。
范文：
Friday Dec. 23, 2005 Sunny
This afternoon I went to play basketball with some of my good friends happily.
At the very beginning, I didn‘t want to go playing basketball though my friends invited me to. I was (had been) in a bad mood the whole afternoon because I didn‘t do well in the math exam. With their comfort and encouragement, I went with them. However,
I was just one of the audience. I dare not have a try because I was afraid that I couldn‘t play well. Encouraged by my good friends, I picked up the basketball and played with them. And luckily I got scores. I felt very excited.
