# How can I schedule a crontab job to run every week on Sunday?

## Problem

I’m attempting to find out how to execute a crontab job on Sunday every week. I believe the following should work, but I’m not sure I understand. Is the following statement true?

``````5 8 * * 6
``````

## Solution #1

A description of the crontab format may be found here.

``````# 1. Entry: Minute when the process will be started [0-60]
# 2. Entry: Hour when the process will be started [0-23]
# 3. Entry: Day of the month when the process will be started [1-28/29/30/31]
# 4. Entry: Month of the year when the process will be started [1-12]
# 5. Entry: Weekday when the process will be started [0-6] [0 is Sunday]
#
# all x min = */x
``````

As a result, your 5 8 * * 0 would start at 8:05 every Sunday.

## Solution #2

You can use either of these to have a cron run on Sunday:

``````5 8 * * 0
5 8 * * 7
5 8 * * Sun
``````

The number 5 8 denotes the time of day when this will occur: 8:05.

In general, if you want to do something on Sunday, make sure the 5th column has either 0, 7 or Sun in it. Because you had six people, it was held on Saturday.

The format for cronjobs is:

`````` +---------------- minute (0 - 59)
|  +------------- hour (0 - 23)
|  |  +---------- day of month (1 - 31)
|  |  |  +------- month (1 - 12)
|  |  |  |  +---- day of week (0 - 6) (Sunday=0 or 7)
|  |  |  |  |
*  *  *  *  *  command to be executed
``````

To double-check your cron expressions, you may always use crontab.guru as an editor.

## Solution #3

The crontab file should be formatted as follows.

{minute} {hour} {day-of-month} {month} {day-of-week} {user} {path-to-shell-script}

So, to run each Sunday at midnight (Sunday is generally 0 but 7 in some odd circumstances), do the following:

``````0 0 * * 0 root /path_to_command
``````

## Solution #4

The crontab website displays the results in real time: https://crontab.guru/#5 8 * * 0

## Solution #5

You must make sure that your cron values are inside the ranges when specifying them. Some crons, for example, employ a 0-7 range for the day of week, with 0 and 7 representing Sunday. We don’t have any (check below).

``````Seconds: 0-59
Minutes: 0-59
Hours: 0-23
Day of Month: 1-31
Months: 0-11
Day of Week: 0-6
``````
