A:
Use $(...) to execute a command and return the output as a string:
[[ $(date '+%a') == "Sun" ]]

Better make that command "LC_ALL=C date +'%a'" or that shell script will cease to work as soon as someone runs it with a non-English locale set.

Or better yet, use `%w` so that it gives you a number.

A:
You can use the date +%u to get the day number of the week... 1 - 7 with Monday being 1 that way you should not have an issue with non-english locales
