### Answer Yes, your conversation flow agent can access current date and time information using system default dynamic variables. [(1) ]() Retell provides several built-in variables for time-based logic: -

{{current_time}}

- Current time in America/Los_Angeles -

{{current_time_[timezone]}}

- Current time in a specified timezone (e.g.,

{{current_time_Australia/Sydney}}

) -

{{current_hour}}

- Current hour in America/Los_Angeles -

{{current_hour_[timezone]}}

- Current hour in specified timezone -

{{current_calendar}}

- 14-day calendar in America/Los_Angeles -

{{current_calendar_[timezone]}}

- 14-day calendar in specified timezone For your office hours use case, you can use equation-based transition conditions to check if the current time falls within business hours: [(2) ]()

{{current_hour}} >= 9 AND {{current_hour}} < 17

This allows you to route calls differently based on whether the clinic is open or closed. For public holidays, you would need to: 1. Pass holiday dates as custom dynamic variables (e.g.,

{{holiday_dates}}

) [(1) ]() 2. Use equation conditions like

"December 25, January 1" NOT CONTAINS {{current_date}}

[(2) ]() You can combine these conditions in your conversation flow to prevent transfer attempts outside office hours and instead offer alternatives like voicemail or callback scheduling.
