Sure! The beginning of each word is different:
For "Tuesday", to make the "T", push the tip of your tongue -firmly- against the -back- of your top teeth. To make the "ue", make a tight circle with your lips (like you're trying to whistle). Now, -forcefully- push air out from your lungs!
For "Thursday", to make the "Th", push the tip of your tongue -lightly- against your top teeth.
Push air out -gently- so that it flows around your tongue. It's ok if your tongue moves a bit, but it should basically stay in place because you're not pushing "explosively" like for "T"! The "ur" sound comes from deep down in your throat, almost like an angry dog growling.
