SavvyCal currently attempts to infer the scheduler's conventional "first day of week" based on the locale setting in their browser/OS (Sunday vs Monday). Unfortunately, the locale does not always align with their actual location (if, for example, they set their OS to be "en-US", but they're not actually in the US). This causes our inference to sometimes not align with expectations. It may be necessary to try other location inference methods, such as geolocating IP address.

Original post:
Currently, the default setting for calendars shows Sunday as the first day of the week, which is familiar in the US but less so in other regions where Monday is commonly seen as the first day. This can cause confusion for users outside the US who expect Monday to be the start of the week.
To improve the global user experience, it would be helpful if the default start day of the week adjusted based on the user’s region, similar to how time zones are automatically detected and set. For example, if the time zone is outside the US, Monday could be set as the default first day of the week.
