# Dates

In Anytype, **every date is its own Object**. When you mention `@today`, set a Due Date, or open a Calendar view, the dates aren't just text or metadata — they exist as Date Objects in your Channel that you can open, link to, and use as a hub for everything happening on that day.

Click on a date anywhere — a property value, a mention, a calendar slot — and you open the Date Object. You'll see:

* Every Object that mentions this date
* Every Object created on this date
* Every Object whose Date Property points to this date
* Discussion posts and Chat messages timestamped to this date

This makes the Date Object a **temporal index** — a single page that shows you everything connected to a specific point in time.

## Three ways dates appear

Dates show up in Anytype in three forms:

#### 1. Mentions in text

You can type `@date` or `/date` to open the date picker and select date (or choose **Today**).

The mention appears as a clickable date — click to open the Date Object.

#### 2. Date Properties

You can add a Date Property to any Type — Due Date, Started On, Published, Last Reviewed, Birthday. The Property accepts a date (and optionally a time):

* **Date only** — useful for due dates, birthdays, deadlines
* **Date and time** — useful for meetings, events, time-stamped logs

Click the Date Property value on an Object to open the date picker and change it.

#### 3. Automatic date Properties

Every Object has built-in date Properties Anytype manages automatically:

* **Created Date** — when the Object was first created (immutable)
* **Modified Date** — last time the Object was edited
* **Last Opened** — last time you viewed the Object (per device)

You can show or hide these in any View, filter by them, sort by them, and reference them in formulas.

## Date as Object

Open any Date Object — by clicking a mention, a date Property, or a calendar slot — and you see:

* **Mentions of this date** — every text mention of `@thisdate` across your Channel
* **Objects with this date as a Property value** — every Object whose Due Date, Started, etc. equals this date
* **Objects created on this date** — auto-grouped by Created Date
* **Objects modified on this date** — auto-grouped by Modified Date

Each section is a list you can scan or click into. You can also add notes directly to the Date Object — write a daily journal entry, add a top-of-day plan, log meeting notes — all attached to that day forever.

### Calendar view

Any Query or Collection can switch to **Calendar view** if it includes a Date Property. Click the layout switcher and choose **Calendar**:

* Objects appear on the date matching their selected Property
* Click an Object to open it
* Click an empty calendar slot to create a new Object on that date
* Drag Objects between dates to update their Date Property

You choose which Property powers the Calendar in the View settings — for example, a Tasks Calendar might use **Due Date**, while a Journal Calendar uses **Created Date**.

### Locale-aware date inputs

Date fields in filters and pickers respect your operating system's locale. If your system uses MM/DD/YYYY, that's what you'll see. If it uses DD/MM/YYYY, you'll see that instead.

You can also set this manually in **Vault Settings > Application > Language & Region > Date & Time formats**.

The same setting controls:

* Date format (DD/MM/YYYY, MM/DD/YYYY, YYYY-MM-DD, etc.)
* Time format (12-hour or 24-hour)
* Whether to use relative dates (today / tomorrow) or always show the literal date
* Week start day (Sunday or Monday)

## Tips

{% hint style="info" %}
**Use Date Properties for project timelines.** A project Object with Started, Target, and Completed Date Properties lets you build a timeline View that updates as work progresses.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.anytype.io/anytype-docs/features/dates.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
