Timezone Converter is a browser-based tool that lines up several time zones on a single synchronized timeline, so you can see what time it is everywhere at a glance and pick a slot that works for everyone.

Each zone gets its own column on one shared vertical timeline, and a center reference line stays aligned across all of them — scroll, drag, or move the slider and every column tracks the same moment, with the date shown right alongside the time.

The zones are driven by the IANA time zone database, so daylight-saving transitions are applied automatically and you never have to remember who has already sprung forward or fallen back. Everything runs entirely in the browser, with no sign-up.
