A customer books a call through your Tempe website. Your calendar says 10 a.m.; theirs says 1 p.m. That can be the same appointment, correctly displayed in two places.
The problem starts when a confirmation leaves out the time zone, or someone copies an old time difference into a new invitation.
Check the whole appointment, not just the hour on the screen. Your booking page, messages, and calendars should help both people arrive at the same moment.
Start with where the appointment happens
Separate appointments at a fixed address from calls people can join elsewhere. That decision should guide both the booking settings and the wording beside them.
Imagine a Tempe consultant offering office visits and online consultations. An office visitor needs the Tempe address and local arrival time. An online customer needs to understand the time shown where they will join.
Give those choices clear names before reviewing the time settings. “Consultation” alone may leave someone guessing whether they should travel or wait for a link.
Write a short brief for each appointment type: where it happens, who attends, which staff member owns the schedule, and how the customer joins or arrives. Check the public page against that brief.
Our booking-capacity guide covers gaps, notice periods, and workload. This review asks a different question: does everyone understand when the appointment happens?
Check the Arizona setting behind the schedule
Have the person managing appointments show you the schedule’s time zone. Choose the setting for your actual Arizona location, rather than one whose current hour happens to match.
Most of Arizona does not observe daylight saving time; the Navajo Nation is an exception. NIST’s guidance gives November 1 as the end of U.S. daylight saving time in 2026. A customer elsewhere can change clocks while your Tempe schedule stays put. Read NIST’s daylight saving guidance.
Do not describe your business as permanently “three hours behind” a customer. That comparison needs a date as well as two locations.
The example below holds a Tempe appointment at 10 a.m. on two dates. New York’s displayed hour changes between them. NIST lists the standard and daylight offsets and notes that most of Arizona uses Mountain Standard Time year-round. See NIST’s time-zone table.
Example appointments in 2026
| Date | Tempe | New York |
|---|---|---|
| Oct. 20 | 10 a.m.MST | 1 p.m.EDT |
| Nov. 10 | 10 a.m.MST | NoonEST |
Keep the date with the time-zone comparison.
Make the customer’s selected zone visible
Open the booking page through your website. Find the time-zone label before choosing a slot. Check that it is still readable on a phone and that the surrounding instructions agree with it.
Calendly detects an invitee’s zone and normally displays availability in their local time. Invitees can change that view with its time-zone dropdown. For in-person events, Calendly recommends locking the event to the venue’s zone. Read Calendly’s time-zone guidance.
If you use another provider, ask it to demonstrate the equivalent behavior. Do not assume an embedded calendar follows the same settings as a similar-looking tool.
For the consultant example, review office visits and online calls separately. A sentence beside the office booking link might say “Appointments take place at our Tempe office.” Add the actual address and check the time label within the booking tool itself.
Avoid surrounding a customer-local display with a blanket statement that all times are Arizona time. The page and the widget need to tell the same story.
Compare the confirmation with the calendar entry
Arrange a test appointment with your team, using accounts you control and a test setup where possible. Start at the public link rather than sending yourself an invitation from the administrator’s screen.
Check the date, start time, time zone, duration, and location in the received confirmation. Then use its calendar option and open the resulting entry. Compare the meeting link or street address too.
Google Calendar explains that events appear in the local time zones of the people invited. A different displayed hour can therefore be correct. Google also allows an event to have a specified time zone. Read Google’s calendar guidance.
Ask your maintainer to compare the entries as the same appointment. Changing a correct entry just to make the numerals match can move the meeting instead of fixing the display.
- Booking pageChosen date, time, and displayed zone.
- Received messageConfirmed appointment and how to join or arrive.
- Calendar entryThe same appointment in that calendar’s time zone.
Different local hours can refer to the same moment.
Keep the original message with your test notes. If something is wrong, the exact page, appointment date, and selected zone give your support person more to work with than “the calendar is an hour off.”
Repeat the check across a clock change
Choose a date before a seasonal change and another after it. Use a customer location that actually observes that change. Keep the intended Tempe start time explicit in your notes.
Calendly says it handles daylight saving adjustments. That is still worth verifying through your own website and messages, especially if you added custom reminder text. See its daylight saving explanation.
For recurring appointments, inspect an occurrence on each side of the change. Agree whether the series is meant to stay at the same Tempe hour or follow another location’s working day. Ask the account owner to confirm how the saved series implements that decision.
If the host will travel, include their future location in the review. Check the working hours they intend to offer, rather than assuming a device’s current display tells you what customers will be able to book.
Check changes after the first booking
Follow the rescheduling route from the customer’s received message. Choose another agreed test time, then check the replacement confirmation and both calendar views. Include the meeting link or arrival address in that comparison.
Calendly provides reschedule and cancel links in confirmation emails or calendar invitations. Its scheduling FAQ describes updates to participants’ calendars after those changes. Read Calendly’s scheduling FAQ.
Review any reminder you wrote separately. An old manually typed time inside a message can disagree with the updated appointment details. Give someone responsibility for those templates as well as the booking settings.
Remove test appointments when the check is complete. Save a short record of the dates, zones, messages, and result so another team member can repeat the review.
