When does a 2 week sprint should start/end?

Hi all,

I am having this situation with my team, which varies from my previous experience.

Assuming we start sprints on Wednesdays, I understand day 1 is Wed and day 10 is Tuesday:

Wed(Day 1), Thu (Day 2), Fri (Day 3), Mon(Day 4) Tue(Day 5), Wed (Day 6) , Thu (Day 7), Fri (Day 8), Mon (Day 9), Tue (Day 10).

Thus, the sprint should end on Tuesday and begin with sprint planning on Wednesday. This is how I did in all the companies where we practiced scrum framework under 2 week sprints.
