Sunday week starts would be much appreciated by me too!

I too would like to see this change made. This has been a request by users for the past 4 years. Clearly a feature that would be helpful to a number of users. Additionally, one that requires a relatively small amount of attention as it relates to coding and algorithm changes on Training Peaks end.

Would really like to see this implemented. I don't mind my week showing Monday as my first day, but my coach comes up with the schedule which always starts on Sunday so my weekly stats are always off. Seems like a pretty reasonable feature to add that would go a long way in retaining customers!!

gets my vote

BTW, why is vote button disabled?

I want to add my vote to this request. It seems to be common sense that everyone has their own training schedule and it seems wrong-headed to insist that all must start their training on Mondays. We're not all alike and for some, this just doesn't fit our routine. The best thing to do would be to give athletes and coaches to opportunity to choose their own preferred start for their training week.

Just in case it's the 95th request that makes this happen, please allow this change in the calendar!

I really want this

It's stupid and annoying to not have Sunday as the first day of the week. It throws me off of my other training calendars for me and my athletes. Please get off your butt and at least give us the option. It's far more important than any other belks and whistles tou might think about adding.

Agree that this change is needed.

Well Ben (Admin, TrainingPeaks),
If it was on your current roadmap, you might get more subscribers. Just sayin.

Agreed, where is this update??? Might upgrade account if the calendar was more like Strava.

Please allow us to choose the start day of the week. All my other calendars have this choice and my display week starts with a Sunday. This is a very easy change for your developers to make.

How is it that since 2015 that this feature still has not been implemented? AGREED!!

The lack of this functionality is what has prevented me from subscribing to your premium offering, instead using competitors. I check back every few months to see if you've done it, but no luck in years. I'm sure I'm not alone in this. It would be very simple to develop this functionality.

EVERY other calendar I use starts the week on Sun. TP is the oddball, and it is hard to reconcile with other calendars.

Just in case additional feedback is helpful. It would be much appreciated to have the option to change the calendar to start either on Sun or Monday. As other users reported, given that most other calendars start on Sunday it is quite a frustration to not be able to match the training calendar the same way.
Thanks for your consideration.

TP closed the vote on this in 2015, please consider going over and commenting and voting on the following thread:

This really needs to be fixed.

Definition from Merriam Webster:
Sunday: the first day of the week
Monday: the second day of the week

Also, why have you disabled the Vote button for this?
