★☆☆☆☆ pakistan village Vlogs · Jul 14, 2026

Calendar app icon show incorrect date. Always show Fri 31 how to fix it ?

★☆☆☆☆ Hamedayoo Suchiang · Sep 21, 2026

Local events are only display in the language of the selected region so if you're in India and don't speak hindi then you can't change to english.

★☆☆☆☆ Santhosh K · May 28, 2026

Need this missing feature! Holiday names are displayed only in the local language of the selected region. Ex: India holidays appear only in Hindi & Japan holidays appear only in Japanese. This can be difficult for users who use English / other languages. Please add an option to choose the holiday display language independently of the region. It would improve accessibility for international users. If you also need this feature, please click "Yes" for "Was this review helpful?"
