Starts At helps people figure out when an event starts in their own timezone.


Planning an event for people from different timezones can be confusing. People often have trouble figuring out when something starts in their own local timezone.

Starts At helps people attend conference calls, online seminars, or webinars. It can also help with software releases and big announcements.

Here's how it works:

  1. Use the Starts At homepage to create a link with your event's time, date, and timezone.
  2. Copy and paste the Share Link from the homepage whever you'd like to share it. You can paste it into an email or publish it on a webpage.

You're done!

People who click the Share Link will see the time of your event in their local timezone. This makes it easier for them to plan for your event and more likely they will attend.


  • Avoid linking the words "here" or "click here" (why?). Instead use phrases like "see in your timezone" or "see the time in your local time". Put the time your event will start in its own timezone next to the link.


  • Use timezone abbreviations like ET instead of EST or EDT for Eastern Time. It's easy to get confused between EST and EDT especially for events that are far in the future. Getting the wrong one also causes confusion for your attendees.

  • Create links to Starts At programmatically if you'd like.

    • The t= parameter accepts a variety of formats like 12 hour time and numbers with or without the colon.

      All of these work: 1600, 16:00, 4:00 PM, 4PM

    • The d= parameter needs a date in ISO 8601 format, the best format.

    • The tz= accepts any timezone from The Time Zone Converter or any TZ database name, sometimes known as IANA zones.
