For starters, we've shipped some extra shading on the weekends to help differentiate it from weekdays (h/t Csaba Rakasz)
I had one more event, where I could actually confirm that the event scheduler did not intend to schedule for Sunday, but they were "tricked" by the Sunday shown as the first day of the week. Their location South Africa. Of course I have other calls when the scheduler just didn't show up. It is hard to tell whether it was because of the "first day of the week" confusion or just a regular no-show. I did notice a higher number of no-shows on Sunday, which makes me think more people get tricked by this. I would appreciate your attention to this issue, as this might even be a bug.
Csaba Rakasz: oof, not good, sorry that happened! Interestingly, South Africa is included in the list of countries that use Sunday as the conventional "first day of week" (according to the Unicode CLDR database). The solution here might be to try to more strongly call out the day of week to hopefully alleviate confusion (especially when it's Sunday or Monday). On a separate note though, we are currently inferring where the visitor is based on their browser/OS locale, which might be skewed toward western countries (if folks are setting their browser language to en-US, for example). Going to look into what it would take to use different method for location inference, like locating their IP address.
Derrick Reimer That would be great Derrick. Thanks. My browser is set to en-US as well, even though I am located in Hungary.
Derrick Reimer I also have a suggestion for you. You could color Saturday and Sunday with a slightly darker color. This is a well recognized sign of the weekend days. So even if the default first day of the week calculation didn't work well, or the user got confused, these additional clues, could offer a quick feedback to the scheduler about what day they are looking at. Just a quick thought ;)
Csaba Rakasz: I like it!
Hey James Weber! This should actually be happening already. We auto-detect locale from the browser (OS) settings and derive the first day of week from the Unicode CLDR mappings. Have you heard confusion from schedulers?
Derrick Reimer Hi! I am experiencing the same problem. Yes. I heard from clients that they scheduled calls for the "first day of the week" without even looking, and later turned out that the first day was Sunday, even though they thought it was Monday. I also checked on my own system, and I access a link I have in an incognito window, or regular it shows Sunday as the first day of the week even though I am in CET, and location is set to Hungary (where Monday is the first day of the week).
Csaba Rakasz: Thanks, we'll have a look! Aside from Hungary, do you happen to know the countries for the folks who have expressed confusion?
Derrick Reimer I tried several locations using VPN and the first day of the week never changed. I also tried several browsers and the first day of the week never changed for me either using my own set up from Hungary.
For the moment, we are rolling with our current detection scheme + darkening the weekends (to provide an additional visual cue).
