Time Zone Converter | World Clock & Meeting Planner

Quick Start Guide

  1. Select zones: Choose From and To time zones.
  2. Enter time: Set the source local time to convert.
  3. Use planner views: Use the Planner and World Clock tabs to find meeting overlap.

Understanding Time Zones

One converter, three views

The From/To conversion, Meeting Planner overlap windows, and World Clock are all always available — there is no mode switch. Meeting Planner settings and the Planner/World Clock tabs use whatever "From Time Zone" is selected above.

Why the UTC offset can differ from what you expect

A time zone's UTC offset can shift by an hour during daylight saving time, and the specific date being converted determines which offset applies — that's why the offset shown here is calculated for the actual date of the conversion, not a fixed year-round value.

What this calculator does not cover

This converts a single point in time between zones and suggests meeting overlap windows — it does not track recurring events across DST transitions or handle historical time zone rule changes before the data your browser ships with.

Features

Multiple Views: Converter, Meeting Planner, and World Clock — all always available, no mode switch needed.

DST Aware: Applies daylight saving changes automatically.

Meeting Actions: Copy/share output and create calendar links.

Export: Download conversions as JSON/CSV/PDF.

Common Use Cases

Global Team Meetings: convert a proposed meeting time for all participants and find overlap windows for recurring syncs.

International Travel: translate itinerary times to local destination time and avoid scheduling confusion around DST changes.

Event Planning: coordinate live events for distributed audiences and share the canonical converted schedule text.

Frequently Asked Questions

Time zones are based on offsets from Coordinated Universal Time (UTC). Our calculator automatically handles daylight saving time (DST) adjustments for accurate conversion.
Yes. The Suggested Overlap Windows section always shows meeting times using your selected workday range and meeting duration, and the World Clock section lets you monitor multiple zones continuously — both are available alongside the main converter, no separate mode needed.
UTC (Coordinated Universal Time) is the world's primary time standard. All time zones are expressed as UTC+ or UTC- offsets. For example, New York (EST) is UTC-5 in winter, UTC-4 in summer (EDT). This calculator converts any time to its UTC equivalent automatically.
The Time Slider (on the Planner tab) lets you visualize the same moment across multiple time zones side by side on a 24-hour timeline, making it easy to see at a glance how work hours line up for a distributed team — complementary to the Suggested Overlap Windows section, which ranks specific meeting-time candidates for you.
The World Clock view shows current times in multiple time zones at once. Add time zones to see their current times simultaneously. This is useful for monitoring times across different locations in real-time.
Yes. In guest mode you can export your calculations to JSON. Signing in adds PDF and CSV export. Click the export button to download your results — useful for record-keeping, sharing, or importing into other tools.
Yes. Your calculation history is saved automatically. As a guest you can keep up to 50 calculations per workspace on your device. Sign in for free to keep up to 100 per workspace and access them from any device.
Yes. The Time Zone Converter is free to use with no sign-up required. A free account adds more calculation history, multiple workspaces, and access to your saved data from any device.
