Regarding the issue of the date being off by one year near the end of the year
Hello. This is Wakui from the Development Group 1.
This time, I would like to talk about the issue of the date being off by one year near the end of the year.

environment
Xcode version: 15.4

Symptoms
Only the display at the end of the year was san marino email address off by one year. So I thought "HAHA! No way!" and tried to display the whole year from now in print.

It was definitely off. But it seemed to be displaying correctly for other periods. So, was it just the 29th to 31st of December every year that was wrong? I wondered, and checked the end of 2025 and 2026 as well.

Apparently it's not a specific period that's off by a year, but rather the period that starts to shift by a year is getting a day earlier?
