Timezones and offsets

When you install Simply Schedule Appointments and step through the wizard or the settings for the first time, we do our best to guess your correct timezone. Most of the time this works pretty well, but sometimes, depending on your browser, device, and settings, we’re not able to accurately guess your correct timezone.

If we aren’t able to correctly guess your timezone, then an offset will be selected. An offset is the number of minutes or hours your current timezone is ahead of or behind GMT or UTC. The setting will often look something like one of these:

  • Etc/GMT
  • Etc/GMT0
  • Etc/UTC-9
  • Etc/UTC
  • Etc/UTC+9
  • UTC
  • GMT
  • GMT+0

We generally recommend that you change your timezone setting to use a timezone for your country and region instead of using the offset. Offsets are not affected by Daylight Saving, summer time, local law changes, etc. So if you select an offset instead of a timezone, you might find that once Daylight Saving begins or ends, that all of your scheduled appointment times are off by an hour.

We use the standard list of timezones from IANA (Internet Assigned Numbers Authority). The timezones are usually the name of a region followed by the name of a city/state/province/island/country in that region, like these:

  • Africa/Cairo
  • America/Los_Angeles
  • Antarctica/South_Pole
  • Asia/Calcutta
  • Atlantic/Reykjavik
  • Australia/Melbourne
  • Europe/Amsterdam
  • Indian/Maldives
  • Pacific/Honolulu

In some cases, the common names of the timezones are available as well, like these:

  • US/Eastern
  • US/Pacific
  • Canada/Mountain
  • Canada/Central
  • Mexico/BajaNorte

In other cases, the timezone is just the name of a country like these:

  • Turkey
  • Singapore
  • Portugal
  • Poland
  • Japan
  • Israel

There are hundreds of official timezones around the world, so we provide a handy search to help narrow down the choices. Just type into the field at the top of the dropdown control to narrow down the list of options:
