Following is the format of the crontab file.

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

So, to run each sunday at midnight (Sunday is 0 usually, 7 in some rare cases) :

0 0 * * 0 root /path_to_command

To have a cron executed on Sunday you can use either of these   5 8     0 5 8     7 5 8     Sun   Where 5 8 stands for the time of the day when this will happen  8 05   In general  if you want to execute something on Sunday  just make sure the 5th column contains either of 0  7 or Sun  You had 6  so it was running 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   You can always use crontab guru as a editor to check your cron expressions

When specifying your cron values you ll need to make sure that your values fall within the ranges  For instance  some cron s use a 0-7 range for the day of week where both 0 and 7 represent Sunday  We do not check below    Seconds  0-59 Minutes  0-59 Hours  0-23 Day of Month  1-31 Months  0-11 Day of Week  0-6   reference  https   github com ncb000gt node-cron
