# Cron patterns

Schedules for wormholes, promocodes, and autogenerators

Used in [wormholes](/eng/guide/wormholes.md), [promocodes](/eng/guide/promocodes.md) (resetting uses), and [autogenerators](/eng/guide/autogenerators.md).

## Cron pattern syntax

```
// ┌──────────────── (optional) seconds (0 - 59)
// │ ┌────────────── minutes (0 - 59)
// │ │ ┌──────────── hour (0 - 23)
// │ │ │ ┌────────── day of month (1 - 31)
// │ │ │ │ ┌──────── month (1 - 12, JAN-DEC)
// │ │ │ │ │ ┌────── day of week (0 - 6, SUN-Mon) 
// │ │ │ │ │ │       (0 to 6 are Sunday to Saturday; 7 is Sunday, the same as 0)
// │ │ │ │ │ │
// * * * * * *
```

## Quick examples

#### This runs every minute

\* \* \* \* \*

#### This runs every Sunday

0 0 0 \* \* 7

#### Every 30 minutes from 9 to 17 o'clock

0 \*/30 9-17 \* \* \*

#### Monday to Friday at 11:30

00 30 11 \* \* 1-5

#### Every 10 minutes

0 \*/10 \* \* \* \*

#### At midnight

00 00 00 \* \* \*

#### You can also use the following "nicknames" as a pattern.

| Nickname  | Description                              |
| --------- | ---------------------------------------- |
| @yearly   | Runs once a year, i.e. "0 0 1 1 \*".     |
| @annually | Runs once a year, i.e. "0 0 1 1 \*".     |
| @monthly  | Runs once a month, i.e. "0 0 1 \* \*".   |
| @weekly   | Runs once a week, i.e. "0 0 \* \* 0".    |
| @daily    | Runs once a day, i.e. "0 0 \* \* \*".    |
| @hourly   | Runs once an hour, i.e. "0 \* \* \* \*". |
