What is World Time Buddy?

World Time Buddy is a time zone converter, world clock and meeting planner. Locations are stacked in rows of hour tiles, so reading down a column converts a time across every zone, and a selected time range can be sent to a calendar or shared as a link. The website has been free with all features since the maker ended paid subscriptions in May 2022. There are also iOS and Android apps, listed in the stores as Time Buddy, and embeddable widgets for websites.

World Time Buddy has a free plan. Paid plans start at $2.99 in-app upgrade in the iOS app (billing basis not shown). See every plan

Key features

Hour-tile time comparison
Add locations by searching for places or time zones such as UTC, reorder them by dragging and mark one as home. Each location gets a row of hour tiles aligned with the others.
Select and share a time range
Click and drag across the hour tiles to pick a range, then open it in Outlook, iCal, Google Calendar or Gmail, copy it to the clipboard, or create a public event page.
Google Calendar overlay
Signed-in users can overlay Google Calendar above the hour tiles to find open slots. The mobile apps can show the device's calendars in the same position.
DST warnings and weekend marking
Daylight saving warnings appear a week before a change. Weekends are highlighted, including in countries where the weekend is not Saturday and Sunday.
12-hour, 24-hour or mixed format
Hours can be shown in 12-hour or 24-hour format, or in a mixed mode that uses each location's native format.
Embeddable widgets
A world clock widget and an event widget can be placed on a website. Both detect each visitor's time zone, and the event widget shows the event in the visitor's local time.
