When you start using Simply Schedule Appointments, 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 timezones.

If we aren’t able to correctly guess your timezone, then an offset using UTC or GMT is given to you. An offset is the number of minutes or hours your current timezones 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 recommend that you change your timezone setting to use a Location timezone instead of using the offset.

Offsets Using GTC or UTC vs. Location timezones

Offsets are not affected by Daylight Saving, summer time, local law changes, etc. You might find that once Daylight Saving begins or ends, that all of your scheduled appointment times are off by an hour.

To make sure that your Booking Calendar is displaying the correct time all year round, we recommend you use a Location timezone.

We use the standard list of Location 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 generalized names of the timezones are available too. Though we don’t recommend them, they look like this:

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

Or, the timezone is just the name of a country like these:

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

Locations time zones are the most recommended especially if you’re using the Region/City type. They’re contextual, and will always be correct to tell you the time in that specific area.

Searching for Your Timezone

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:
