How to Disable Contact Timezone in Sparkforge Calendars

By Sparkforge Support Team ·Last reviewed May 3, 2026

To force every appointment into your business timezone, enable Disable Contact Timezone in Settings, Business Profile. Contacts will no longer see a timezone selector when booking.

By default, the Sparkforge calendar widget lets contacts pick their own timezone when booking. That is helpful for nationwide service businesses, but confusing for local businesses where every appointment should be in the shop's local time.

What contact timezone does

With contact timezone enabled (default), a contact in New York booking a 5pm slot with a San Francisco shop sees 5pm EST — the shop sees 2pm PST.

With contact timezone disabled, the same contact books at 5pm PST. Every appointment lands in the sub-account's timezone, no matter where the contact is.

Disable contact timezone

Open Settings from the sidebar.
Click Business Profile.
Scroll to the General section on the right.
Check Disable Contact Timezone.
Save.

The timezone dropdown will disappear from the calendar widget on the next page load.

Set your business timezone

Before disabling contact timezone, confirm the sub-account timezone is correct. Otherwise every appointment lands in the wrong zone.

Open Settings > Business Profile.
Find the Time Zone field under Business Physical Address.
Pick the local timezone for the business.
Save.

When to use this

Single-location service businesses where customers walk in.
Shops near timezone borders that want to avoid confusion.
Tourist towns where visitors from other zones often book wrong times.

Frequently Asked Questions

Will disabling contact timezone affect existing appointments?

No. Existing appointments keep the timezone they were booked in. Only new bookings go through the locked-down widget.

Where do I set the business timezone?

Settings > Business Profile > Time Zone, found under the Business Physical Address fields. This is the timezone all bookings will use once contact timezone is disabled.

Can I disable contact timezone for one calendar but not others?

No. The Disable Contact Timezone setting applies to the entire sub-account. All calendars in that location use the same rule.

What do contacts see when contact timezone is disabled?

The timezone dropdown disappears from the calendar widget. Contacts pick a date and time in your business timezone, with no option to change it.
