### Answer Retell provides default system variables that you can use directly in your prompts, begin messages, tool configurations, and other supported fields without any additional setup. [(1) ]() To reference the current day, use the

{{current_time}}

variable, which displays the current time in

America/Los_Angeles

timezone in this format: "Thursday, March 28, 2024 at 11:46:04 PM PST". If you need the current time in a different timezone, use

{{current_time_[timezone]}}

where you replace

[timezone]

with your desired timezone (for example:

{{current_time_Australia/Sydney}}

) . For a 14-day calendar view, you can use

{{current_calendar}}

for

America/Los_Angeles

timezone or

{{current_calendar_[timezone]}}

for other timezones. These system variables are automatically available—no configuration required. Simply insert them into your prompts using the double curly brace syntax.
