Meeting time-zone tools compared (2026): an honest review of what each one actually does well

Why this review includes competitors

WorldClockTools publishes its own meeting planner and time zone converter. A review that only concludes "use ours" would be useless, so this one says where another tool is the better choice.

It is the companion to our meeting across time zones playbook, which covers the underlying rules. This post is about which tool to open for a given job.

Tools covered, alphabetically: Calendly, Every Time Zone, Google Calendar's time-zone settings, timeanddate.com, World Time Buddy, and our own tools. Feature and pricing details were checked against each product's public site in November 2026; products change, so confirm on their pages before you pay for anything.

The short version

• Convert one time, once: Google Calendar's time-zone settings if you are already in it; otherwise any converter, including timeanddate.com or our time zone converter.
• Pick a time across three or more zones and share it: World Time Buddy, Every Time Zone, or our meeting planner (ranked hours, a calendar file and a share link).
• Check how a recurring meeting shifts across DST changes: find the weeks when the zones change their clocks on different dates (the 2027 dates are in a separate post), then check one occurrence in each of those weeks with a converter that takes a date, such as our time zone converter.
• Let outside people book a slot on your calendar: Calendly or a similar booking tool. The other tools here do not do this.
• Look up a country's DST rules or history: timeanddate.com, which has published this kind of reference since 1998.

timeanddate.com

The longest-running site in the category, launched in 1998. It covers current local time, DST rules, transition dates and historical offsets for most places on Earth, plus calendars and sun and moon data.

Strengths. Depth of reference data. It runs a time-zone news section that reports government clock-change decisions, which matters in a year like 2026 when Canadian provinces, Morocco and Cuba all changed their rules. Its historical lookups go back further than most free tools.

Weaknesses. The meeting planner works but takes more steps than single-purpose schedulers. The free site carries advertising; an ad-free supporter subscription is available.

Best for. Reference questions: "When does Chile change its clocks in 2027?" or "What was Beirut's UTC offset in March 2023?"

World Time Buddy

A visual scheduler that lines up several cities' hours side by side.

Strengths. The colour-coded grid (working hours, early or late, night) is quick to read. You can drag across the grid and see every city update, and the shareable link keeps the chosen time and cities. The free tier covers casual use.

Weaknesses. The free tier limits how many cities you can show at once; more cities need the paid plan. It shows one day at a time, so it does not show how a recurring slot changes across DST transitions.

Best for. Three or four cities, one meeting, everyone looking at the same picture.

Every Time Zone

A minimal visual scheduler: drag a marker along a timeline and every listed zone shows the equivalent local time.

Strengths. Very little to learn, works in a mobile browser, and produces a shareable link.

Weaknesses. Fewer visual cues than World Time Buddy, no view of DST changes over time, no team or calendar features.

Best for. Sending a single link that answers "is 3 pm Pacific reasonable for everyone?"

Calendly

Not a time-zone tool as such, but a booking tool that handles time zones correctly as a side effect.

Strengths. You publish your availability once; other people pick a slot, and the booking page shows the times in their zone. Both sides get a calendar invite in their own zone.

Weaknesses. It answers "here is my availability, pick a slot", not "find a time that suits these four named people". For internal ad-hoc meetings it is more machinery than you need.

Best for. External bookings: sales calls, support sessions, interviews.

Pricing. A free plan exists. Paid plans started at about $10 per seat per month on annual billing in November 2026 (calendly.com/pricing).

Google Calendar (Settings → Time zone, and World clock)

Google Calendar can show a secondary time zone as a second column next to your week view, and a world-clock panel for a few pinned cities.

Strengths. It is already where many people schedule. No extra tool, no context switch.

Weaknesses. The secondary column is one extra zone, not a multi-zone comparison, and the world clock is a reference panel rather than a way to pick a time.

Best for. Someone who works with one other zone every day, such as an engineer in San Francisco reporting to a manager in London.

WorldClockTools: meeting planner and time zone converter

Where we are a good fit.

• The meeting planner ranks the hours of the day for a team's cities and working hours and exports the chosen slot as a calendar (.ics) file. Its share links store the chosen hour in UTC, so the link shows the right local time on any device, in any zone.
• The time zone converter takes a date as well as a time, so you can check what a meeting becomes on a specific future day, such as a week when U.S. and European clocks are out of step.
• The DST tracker lists each country's next clock change, which helps when booking a quarterly meeting away from those weeks.

Where we are not the best fit.

• The meeting planner works at today's offsets. It does not chart how a recurring meeting moves across the year; you check the transition weeks one date at a time in the converter.
• We have no native mobile app; the tools are web pages.
• For dragging one meeting across four cities, World Time Buddy's grid is quicker to read than ours.
• We do not do booking, which is Calendly's job.
• For deep historical time-zone lookups, timeanddate.com has more data.

Pricing. Free. The meeting tools have no sign-up and no advertising.

Mistakes we see most often

• Using a booking tool for internal scheduling. Calendly works well for outsiders choosing from your availability. For finding a slot among four colleagues, a side-by-side view is faster.
• Using a one-day view for a recurring meeting. A grid that is right for this week can be wrong for two or three weeks in March and one week in late October or early November, when U.S. and European clocks change on different dates. Check an occurrence in each of those weeks before fixing a recurring time.
• Sending "15:00 EST". For about eight months of the year New York is on EDT, so the label is wrong. Send a link, or name the zone in full ("15:00 America/New_York").

The reasoning behind these points, including the DST drift weeks and when follow-the-sun handoffs work, is in our meeting across time zones playbook.

FAQ

What is the best free time-zone meeting tool?

It depends on the job. For a one-off meeting across three or four zones, World Time Buddy, Every Time Zone or our meeting planner all work. For checking how a recurring meeting shifts across DST changes, look up one occurrence in each transition week with a converter that takes a date, such as our time zone converter. For letting outsiders book time with you, Calendly's free plan.

Is timeanddate.com still a good reference?

Yes, for DST rules, transition dates and historical offsets. For quickly finding a meeting slot, a dedicated scheduler is usually faster.

When should I use Calendly instead of a meeting finder?

Use Calendly when outside people need to choose a slot from your availability. Use a meeting finder when you know who is attending and need a time that works for all of them. Many teams use both.

Does World Time Buddy handle DST?

It applies the correct offset for the date you are looking at. It does not show how a recurring meeting will shift over the following months; to check that, look at the meeting on a date inside each DST transition week.

What works for teams spread across many time zones?

Beyond about eight hours of spread there is often no slot inside everyone's working day. At that point the answer is usually to move most work to written, asynchronous updates and keep one or two meetings, rotating who gets the inconvenient hour.
