How to Use

Our all-in-one timezone converter provides a visual timeline to compare times across multiple time zones. Here's how to use it:

  1. Default Timezones: Your local timezone is automatically detected and set first, along with EST (US) and GMT (UK) by default. All 42 time zones are available in the dropdown.
  2. Add More Timezones: Click the "Add Timezone" dropdown to select additional timezones. The list shows zones not already added.
  3. Select Date: Use the date picker. For today, current time updates in real time. For other dates, midnight in the first zone is used as reference.
  4. Navigate Hours: Use the < and > buttons to switch between the first 12 hours and the second 12 hours. Default shows the block containing your current time.
  5. Hover to Highlight: Hover a time in your home timezone (first row) to highlight that column across all rows.
  6. Click for Details: Click a time to open a panel with the exact time in all selected timezones.
  7. Remove Timezones: Click "Remove" next to a timezone (when more than one is shown) to remove it.
  8. View Current Times: Each row shows current time for today or the reference time for other dates next to the label.

đź’ˇ Tips:

  • The indicator follows your mouse when hovering to compare times across zones.
  • After clicking, the details panel stays until you choose another time or close it.
  • All conversions run in your browser—nothing is sent to our servers.
  • DST is applied automatically per zone.
