Weird year display bug in December 2025

Hi Routine team,

I think I’ve stumbled onto a bug with how the calendar handles the year-end transition, or maybe it’s a locale-specific issue here in Korea.

When I try to set a duration from December 30th, 2025, to January 4th, 2026, the app labels the years as "2024 to 2025." It’s strange because I’m looking at the December 2025 view, but the notation is showing everything as one year earlier than it actually is.

I’ve seen similar things happen in other apps where the library gets confused between the actual calendar year and the ISO "week-year" (especially since 2026 starts mid-week). It seems like the UI is pulling the wrong year value for that specific date range.

Could you guys take a look at this? It’s a bit confusing to see 2024/2025 labels when I’m trying to plan for next year!

Thanks!
