You have the option to select between 12-hour and 24-hour time format.
The 12-hour time format uses "AM" and "PM" to differentiate between morning and afternoon/evening hours. This format is commonly used in North America and other regions, and it can be helpful for customers who are more familiar with this time format.
On the other hand, the 24-hour time format is used in many countries around the world and uses a 24-hour clock. This format can be helpful if you prefer to use a single time format across all your services, or if your customers are more accustomed to using this time format.
