# Schedules

In addition to sending a message once, you can create a schedule, and we will
publish the message in the given period. To create a schedule, you simply need
to add the `Upstash-Cron` header to your `publish` request.

Schedules can be configured using `cron` expressions.
[crontab.guru](https://crontab.guru/) is a great tool for understanding and
creating cron expressions.

We use `UTC` as timezone when evaluating cron expressions.

The following request would create a schedule that will automatically publish
the message every minute:

```
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Content-type: application/json" \
    -H "Upstash-Cron: * * * * *" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/schedules/https://example.com'
```

All of the [other config options](/qstash/howto/publishing#optional-parameters-and-configuration)
can still be used.

<Info>
  It can take up to 60 seconds for the schedule to be loaded on an active node and
  triggered for the first time.

You can see and manage your schedules in the
[Upstash Console](https://console.upstash.com/qstash).

### Scheduling to a topic

Instead of scheduling a message to a specific URL, you can also create a
schedule, that publishes to a topic. Simply use either the topic name or its id:

```bash
curl -XPOST \
    -H 'Authorization: Bearer XXX' \
    -H "Content-type: application/json" \
    -H "Upstash-Cron: * * * * *" \
    -d '{ "hello": "world" }' \
    'https://qstash.upstash.io/v2/schedules/<TOPIC_ID_OR_NAME>'
```
