# Can I add multiple timezones for my business operation hours? No, you cannot add multiple timezones for your business operation hours. You are allowed to setup only one specific time zone for your Call Me Back configuration. Your customers will see time slots as per their device's time zone. * For example, suppose you have set up business operation hours as 10:00 am to 02:00 pm in the India Standard Time (GMT+5:30) time zone in your Call Me Back configuration. Now, suppose the customer you are calling is in Gulf Standard Time(GMT+4:00). Then they will see time slots like 08:30-09:00 am, 09:00-09:30 am, and so on. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
