Free meeting time tools compared: World Time Buddy vs Every Time Zone vs this tool

If you schedule across time zones regularly, you've probably used one of these three tools. Here is a concrete comparison based on what each one actually does.

World Time Buddy

World Time Buddy is the market leader. It shows a horizontal time grid for multiple cities side by side, color-coded by time-of-day (working hours in green, off hours in yellow/red). You can drag to select a time slot and share a link.

What it does well: the side-by-side grid is immediately readable. The "best time" suggestion is useful. It has a browser extension.

Where it falls short: the free tier now has ads and limited city comparisons. The interface has accumulated complexity over the years. There is no visual globe or map, and no shareable image card.

Every Time Zone

Every Time Zone (everytimezone.com) takes a minimalist approach: a single horizontal timeline showing the current time across a preset list of major cities. You can click to highlight a specific time across all zones.

What it does well: incredibly fast and clean. Great for a quick "what time is it in Tokyo right now" check. No sign-up, no ads.

Where it falls short: you can't add custom cities. The preset list is fixed. There is no overlap indicator, no meeting card export, and no visual map. It's a reference tool, not a scheduling tool.

This tool (Meeting Time Coordinator)

What it does differently: interactive 3D globe with day/night shading, drag-to-select time slider with working-hour overlap indicator, and a shareable PNG meeting card you can copy to clipboard or download.

Strengths: the globe is a genuinely different interaction model - it makes the geographic context of time zone differences intuitive. The overlap indicator is explicit. The meeting card is ready to paste into Slack or email without any extra steps. Fully free, no sign-up, no paid tier.

Weaknesses compared to World Time Buddy: no "best time" AI suggestion, no shareable link (card image only), no calendar integration, no browser extension.

Which one should you use?

• For a quick sanity check on what time it is somewhere: Every Time Zone.
• For scheduling with multiple international stakeholders who need to approve a slot: World Time Buddy (the grid is the most information-dense view).
• For sharing a clean, visual confirmation of a meeting time across cities: this tool (the PNG card is the unique output).
• For teams who want to actually see where everyone is geographically while coordinating: this tool (the globe view).
