I'm running two cron jobs:

This one executes without a problem:

curl -sS http://example.com/cronjob.php?days=1

But this doesn't run at all:

curl -sS http://example.com/cronjob.php?days=1&month=1

Is this because of the ampersand (&)? If yes, how to pass multiple parameters?

Using argv is not an option.

You'll notice that this doesn't exactly work in your shell, either.

What you need to do is put single quotes around the URL, like so:

curl -sS 'http://example.com/cronjob.php?days=1&month=1'

Windows user running curl binaries should use double-quotes instead of single quotes to get multiple query parameters command working.
This works for me - many minutes wasted not understanding why my second parameter wasn't working.
Welp, I feel stupid now. I was also forgetting my quotes. Thanks man.

As an alternative way, you can use \ before & which is a special character for shell. Generally, & is one of special characters that are meaningful for shell.

So, using a backslash [beside Quoting solution] can be a good solution to this problem. more

In your example you can simply apply this command:

curl -sS http://example.com/cronjob.php?days=1\&month=1

➕1 for actually explaining the issue being & behaving as a special character [which as i looked it up on your link indicates 'background job' 🤷]
this was the exact reason that my curl didn't work. thanks!

Try a POST Request 

curl -d "days=1&month=1" www.example.com/cronjob.php

Any particular reason you suggest a POST?
No harm in mentioning it, it's good to know (Although I'll go with GET)
well it just up you you also could do it with a GET request. This is just how i would do it. However this would work, and that is the point :-)
You can not know if it will work - it depends on the script if it looks POST variables or only GET variables.
on the receiving end it wont matter ($_REQUEST) but using an implicit string as URL not sure how post would work. Using GET or REQUEST will retrieve the variables

Here's another way to do a POST request with multiple parameters:

curl www.example.com/cronjob.php -d name=John -d age=30
