I have occasionally convinced teams to adopt both oncall and sprint cycles aligned with Tuesday [1] - the dev teams all loved it. Management was a harder sell, but by and large were happier with the extra days to communicate results/get metrics before their own Friday deadlines.

[1] also Wednesday/Thursdays. Wednesdays were my favorite in good working environments, it felt like running a successful marathon, but it was more prone to falling apart due to short-term thinking.

We have our sprints start on Tuesdays, and our in-hours on-call also runs Tuesday to Monday. Out of hours on-call starts at 5pm Monday.

I'm curious why Tues to Tues for sprints was a hard sell to management?
