Sonoma Calendar date format

Just upgraded to Sonoma (14.0) and Calendar is no longer respecting my system date format setting.

My system date format setting is YYYY-MM-DD, which Calendar previously respected. But it's now, when I press Shift-Command-T ('Go to date') it wants MM/DD/YYYY. I'm guessing it's getting the latter format from my region (Canada). But it should respect the date format.

Other apps (e.g. Mail) are respecting the system date format setting. have no individual application setting for Calendar.

Fix?

Calendar and Reminders in macOS 13 and earlier did NOT respect the Date Format in the Language & Region settings. The reason you saw YYYY-MM-DD in macOS 13 and earlier Calendar and Reminders was because that was the date format Apple had decided to associate with Canada as Region in the Language & Region settings. In macOS 14 Apple has associated the date format MM/DD/YYYY with Canada as Region in the Language & Region settings. I'm not Canadian but have always used Canada as the Region exactly because it was the only one that was associated with the ISO 8601 date format.
