Time Zone Converter is a simple yet powerful Chrome extension designed to help you effortlessly convert time zones right from your browser toolbar.
Whether you’re coordinating meetings across countries, working with a remote team, or simply checking time differences — this tool makes it quick and seamless.
I mostly use it to double-check “next Tuesday 10am Tokyo vs. Seattle” before sending invites—much quicker than opening Calendar.
