How to write a diary: 7 easy steps with examples
To write a diary, pick a notebook or an online diary, write the date, then tell your diary what happened today and how you felt about it. Write in the first person (I, me, my), the way you would talk to a close friend. A few honest lines are enough, and the habit matters more than the length.
How to write a diary in 7 steps
- Choose where you will writeA paper notebook, a diary with a lock, or a private online diary like the one on this page. Pick the one you are most likely to open again tomorrow.
- Write the date at the topAdd the day of the week too. Some people also write the time and where they are. The date is what turns your notes into a diary you can look back on.
- Start with a greeting if you likeMany people write Dear diary, at the top. It makes the page feel like talking to a friend. You can also give your diary a name, or skip the greeting.
- Write what happenedTell the main events of your day in order. You do not need every detail. Pick the parts that mattered.
- Write how you feltThis is the heart of a diary. Were you happy, nervous, bored, proud, upset? Why? Feelings are what you will want to remember later.
- End with a thoughtFinish with what you learned, what you hope for tomorrow, or a simple goodnight. Some people sign their name or initials.
- Come back tomorrowPick a time that fits your day, like just before bed. Writing a little most days is how a diary becomes a habit.
Not sure where to begin? Try three lines: what happened, how it felt, and one thing to remember. That is a complete diary entry.
The simple diary format
A personal diary has no strict rules, but most entries follow the same shape. If you are writing a diary entry for school, the format matters more, and you can see the full layout on our diary entry format page.
| Part | What to write | Example |
|---|---|---|
| Date | Day, date, and time if you like | Monday, March 9, 9:30 pm |
| Greeting | Optional, often Dear diary | Dear diary, |
| Opening | One line about your day or mood | Today was long but good. |
| Body | What happened and how you felt | The main events, in your own words |
| Closing | A last thought or plan | Tomorrow I will try again. |
| Sign off | Optional name or initials | Goodnight, Maya |
Write in the first person because it is your story. Use the past tense for what happened (I went, we laughed) and the present tense for how you feel now (I am still tired, I think she was right).

What to write about in your diary
Some days are full of news. Other days feel empty. Here are things you can always write about:
- Your day. The best moment, the worst moment, and something funny.
- Your feelings. What made you happy, worried, angry or proud, and why.
- People. A friend, a family member, someone new you met.
- Plans and goals. What you want to do this week or this year.
- Memories. A birthday, a trip, your first day at school.
- Lists. Favorite songs, things you are grateful for, places to visit.
- Questions. Things you are wondering about or trying to decide.

How to write a diary in English (tips for learners)
Keeping a diary is one of the best ways to practice English, because you write about things you know and care about. These tips help:
- Use simple past tense for events. I woke up, I went, I saw, I ate, I felt.
- Use feeling words. Happy, excited, nervous, upset, relieved, proud, bored, grateful.
- Use time words to keep order. First, then, after that, later, in the evening, finally.
- Keep sentences short. One idea per sentence is clear and correct.
- Learn one new word a day and use it in your entry.
- Read old entries after a month. You will see how much your English has grown.
| Instead of | Try |
|---|---|
| It was good. | It was the best lunch I have had all week. |
| I was sad. | I felt left out when they made plans without me. |
| We went out. | We walked to the park and fed the ducks. |
Tips to keep writing a diary
- Same time, same place. Linking your diary to something you already do, like getting into bed, makes it automatic.
- Lower the bar. On busy days, write one sentence. It still counts.
- Be honest. Your diary is private. Write what you really think, not what sounds nice.
- Skip the guilt. Missed a week? Just write today's date and carry on.
- Add small details. The smell of the rain, the exact words someone said. These make old entries come alive.
- Keep it safe. Use a diary with a lock, a hiding place, or a diary with a PIN on a shared computer.

Common mistakes when writing a diary
- Trying to write everything. You do not need to list every class and meal. Pick what mattered.
- Only writing facts. A diary with no feelings reads like a timetable. Add how it felt.
- Writing for an audience. If you worry someone will read it, you will hold back. Keep it private so you can be honest.
- Forgetting the date. Without dates, you cannot tell when things happened when you read back.
- Giving up after missing a day. Everyone misses days. Start again with today.

Questions people ask
How do I start writing a diary for the first time?
Write today's date, then a greeting like Dear diary. Introduce yourself in a few lines, as if the diary were a new friend: your name, age, where you live, what you like. Then write about today and how you feel. Your first entry does not have to be long or perfect.
What is the format of a diary?
A diary entry usually has the date (and sometimes the day and time) at the top, an optional greeting like Dear diary, the body where you write what happened and how you felt, and a short closing thought. Some people sign their name at the end. It is written in the first person.
Should I write my diary every day?
You do not have to, but writing most days builds the habit and gives you a full record of your life. Short daily entries work better than long ones once a month. If you miss days, just start again. There is no penalty.
What tense do you write a diary in?
Use the past tense for things that happened earlier, like I went to school and we played soccer. Use the present tense for how you feel right now, like I am tired, and the future tense for plans, like tomorrow I will call her.
How do I keep my diary private?
Keep a paper diary somewhere safe or choose one with a lock. If you write online, use a private diary that does not post anything and can be locked. Our online diary keeps pages in your browser on your device and has a PIN lock for shared computers.
Can I write a diary on my phone?
Yes. You can use an online diary in your phone's browser, like the one on this page, and add it to your home screen so it opens like an app. Your pages stay on that device, so print or save a PDF of entries you want to keep safe.
