Affected app version

1.3.1

Affected Android/Custom ROM version

Android 15, stock

Affected device model

Motorola Moto g64

How did you install the app?

F-Droid / IzzyOnDroid

Steps to reproduce the bug

1. Set app locale to Japanese (or system locale, failing that)
2. Navigate to home screen or add a widget

Expected behavior

In Japanese, the date string should be M月D日（ddd）, without spaces, where ddd is the single-letter weekday abbreviation.

The stock app shows this (Sunday, September 21 → 9月21日（日）).

Actual behavior

Fossify Clock says “日, 21 9月”, which is nonsense in Japanese. It’s probably the result of reusing the British English template ddd, D M instead of the appropriate localized format.

This is expressly against Android’s API reference!

Most callers should avoid supplying their own format strings to this class' format methods and rely on the correctly localized ones supplied by the system. This class' factory methods return appropriately-localized DateFormat instances, suitable for both formatting and parsing dates. For the canonical documentation of format strings, see SimpleDateFormat.
