About
One moment, shown everywhere.
Compare up to five time zones, choose a real instant, and share every local date and UTC offset without an account or calendar connection.
Built for the date-changing part
A meeting can be Tuesday in Seoul and Monday in New York. Mallow Time Zone keeps every row tied to the same absolute instant and always shows the local date, time, IANA zone, and UTC offset together.
DST is a rule, not a guess
The converter ships a versioned IANA time-zone data set and tests daylight-saving gaps, repeated times, half-hour and quarter-hour offsets. The supported planning range is 2022 through 2030 so the bundled rules stay explicit and testable.
Meeting-friendly, not calendar-heavy
Pick 30, 60, or 90 minutes, compare ordinary working-hour hints, copy a clear text summary, share the selected instant, or download a UTC-based calendar file. The tool never needs permission to read your calendar.
Your choices stay close
Time-zone order, primary zone, time format, and duration can stay in this browser. A share link contains only those zone IDs and primary designation, the selected instant, duration, and display format. Read the exact boundary in the privacy policy.

MallowDesk makes small tools that work right away. Use the Mallow Timer for a countdown, the Mallow Word Counter for a draft, the Mallow Typing Test for a speed check, or the Mallow Picker for a quick choice.
