Short weekends and compensation

Good day all,
I have been out for a long time and my time of driving was still with disks.
Now I’m due to start on a project in Denmark. The idea is to work 3 weeks and go home for one week. When I start on Monday am I right to think I must make a 45h rest the first weekend. And then the second I can cut it to 37 hours.? After the third week of work I will go home so there is enough compensation.
We will work 6 days a week 10h a day starting the Monday’s.
So in short:
60h week - 45h weekend- 60h week - 37h weekend- 60h week - week at home.

So the first weekend I need to stop driving at Sa 12:00h so I can start driving at Mo 09:00 (45h)
Second weekend I can work/drive until Sa 18:00 and start at Mo 07:00. (37h)
Week at home is 205 hours

Average working is then 180h in 4 weeks so 45h p week.

Please advise if I’m thinking the right way here.
The whole new tacho is a bit fuzzy
Thanks Ray

After a week off you can do this …
Week 1 = if you start after sunday midnight then your regular weekly rest for this week is covered by the last 45 hours of your week off
Week 2 = this can be a reduced weekly rest for as little as 24 hours
Week 3 = if you start the weekly rest before the sunday midnight at the end of this week then that is a regular weekly rest
