It can be difficult to work out if you can work or not when you are working reasonably ad-hoc and you start getting single days off during the week thrown in like that.
Ask your self these questions in this order to help you to see if you have complied
in the fixed week is there a weekly rest
is that weekly rest a regular or reduced one
is there a regular weekly rest in every other week
is there no more than 144 hours between any 2 weekly rests
