What Day Is It, Zoey by Zoey Tang

Checks dates as you type, fixes the weekday, and rewrites them in your chosen format and language.

⭐Are you the same kind of weird who needs to know what day every date falls on? When you enter 1/23, don't you wish it would magically convert to Friday, January 23, 2026, or whatever format you prefer? Have you ever sent an important meeting email with a mismatched date and weekday, causing confusion? Well, this Firefox extension is for you then!

What Day Is It, Zoey? is a spell-checker for dates Firefox extension I built for myself, and now I am sharing it with you.
