Dealing With Multiple Time Zones

It goes without saying that appointment reminders should say the right time or else you risk hurting your business as opposed to helping. Sometimes getting the time right can actually be tricky. This typically applies if you hold appointments with clients in multiple time zones.

This blog post will outline the steps you should take if your business holds appointments with clients in different time zones.

Step 1) Include the time zone in your messages

The first step is to add the time zone to your messages. This ensures that even if the time that is announced to your client is not in their time zone, they might notice the time zone is different and respond appropriately.

You can do this by including the {{ event.time_zone }} field in your Apptoto messages.

We recommend you add the time zone immediately after the time in the body of the SMS and the call messages. In Apptoto you can do this by clicking on the “Auto Messages” tab and then editing your SMS and call messages. Here is how the message should look after you’ve added the time zone field.

For automatic email messages, you will want to include the time zone in the subject and the body of the message like so:

Step 2) Change the Appointment Page to use “Browser Time”

The “Appointment Page” is the page that client’s see when they click on the link that Apptoto includes in your SMS or Email message (via the {{ }} field). You can customize the time that appears on that page on the “Settings” > “Appointment Page” tab in Apptoto.

You can take advantage of the fact that the browser knows what time zone the client is currently in by using {{ event.start_time | browser_date_and_time }} or {{event.start_time | browser_time }} in the appointment page settings.

Here is what the appointment page then looks like for the client when they click on the link:

Step 3) Tell Apptoto which time zone your client is in

If your client’s time zone is different than your time zone then you need to tell Apptoto which time zone your client is in. There are 4 ways you can do that:

3.a) Segment your client’s time zones by calendar

In other words, have one calendar for each time zone that you have clients in and put the appointments on the correct calendar when you schedule them. While this sounds strange, sometimes it’s the easiest approach. Especially if you already have different calendars for each sales region or for each regional office.

3.b) Or, change the event’s time zone

Some of the calendaring systems that Apptoto integrates with (e.g. Google, Office 365, and Outlook) allow you to specify the time zone for each event. For example in Google, you can change the time zone for an event by clicking “Time zone” to the right of the time on the “Edit Event” screen. Here is a screenshot:

If the time zone of the event is different than the time zone of the calendar then Apptoto shows a dotted-line under the time in Apptoto and if you hover over the time, Apptoto will tell you what time the appointment is in for you and your client.

3.c) Or, include the time zone or zip code in the event’s body or content

You can set the time zone by prefacing the time zone with “Time zone:” in the body of the appointment.

For example, you can put the following in the body of the appointment and Apptoto will use Eastern time when sending the message.

  • time zone: EDT

This works great if you’re using a system like or Acuity Scheduling to book your appointments. Those systems can be configured to add the client’s detected time zone into the body of the appointment.

Apptoto will recognize all standard time zone names and abbreviations.

Alternatively, you can put the zip code in the appointment (US Only). For example:

  • zip: 10001

NOTE: Be sure to turn on the “Use time zone found in event body” option if you want to use this approach.

3.d) By setting your contact’s zip code (US Only)

Lastly, if you’re using Apptoto’s contact matching feature, then Apptoto can detect the client’s time zone by using the zip code listed in the contact record.

Our Salesforce users love this approach because typically the contact or lead record in Salesforce will have zip code properly recorded.

You can also set the zip code for each contact in Apptoto on the “Contacts” tab.

NOTE: Be sure to turn on the “Use time zone based on contact zip code (US Only)” feature if you want to use this approach.
