Hello Łukasz,
welcome to the rufus-scheduler mailing list.
On a GNU/Linux or OSX machine you can fire up a terminal and hit "man 5
crontab", it will describe how to use a crond crontab, which rufus-scheduler
tries to mimic for its cron jobs.
For example:
```
# every tuesday every hour from 0600 to 2200
scheduler.cron '0 6-22 * * 2' do
print "hourly test"
end
```
You can use commas and dashes.
Best regards,
--
