how exactly this cron parser is working here?

[siddhant3030]

I have tried to import Crontab.CronExpression

Then in iex shell I used this command to parse the corn expression

Crontab.CronExpression.Parser.parse ("* * * * MON-TUE")

But this giving me this output {:ok, ~e[* * * * 1-2 *]}

Crontab.CronExpression.Parser.parse "* * * * *"
{:ok,
  %Crontab.CronExpression{day: [:*], hour: [:*], minute: [:*],
  month: [:*], weekday: [:*], year: [:*]}}

How this example is working?
