How do I set the time format (12 - hour or 24 - hour) on a plastic table clock?

Jan 12, 2026

As a supplier of Plastic Table Clocks, I often receive inquiries from customers about various features and functions of our products. One of the most common questions is how to set the time format (12 - hour or 24 - hour) on a plastic table clock. In this blog post, I'll guide you through the process step - by - step, and also share some related information about our clock products.

Understanding the Basics of Time Formats

Before we dive into the setting process, it's important to understand the difference between the 12 - hour and 24 - hour time formats. The 12 - hour format divides the day into two 12 - hour periods: AM (ante meridiem, from midnight to noon) and PM (post meridiem, from noon to midnight). For example, 3:00 PM represents 15:00 in the 24 - hour format. The 24 - hour format, on the other hand, uses a continuous count from 0:00 (midnight) to 23:59, eliminating the need for AM and PM designations.

General Steps to Set Time Format on a Plastic Table Clock

The process of setting the time format can vary slightly depending on the model of the plastic table clock. However, most of our plastic table clocks follow a similar set of steps:

Step 1: Locate the Setting Button

On the back or side of the plastic table clock, you'll find a small button labeled "SET" or something similar. This button is used to enter the setting mode. Press and hold this button for a few seconds until the time display starts to flash. This indicates that the clock is now in the setting mode.

Step 2: Navigate to the Time Format Setting

Once in the setting mode, use the "UP" and "DOWN" buttons (usually located near the "SET" button) to navigate through the different setting options. Look for an option that indicates the time format, which might be labeled as "12H/24H", "TIME FORMAT", or something similar. When you find this option, the display will show either "12H" or "24H".

Step 3: Select the Desired Time Format

Use the "UP" or "DOWN" buttons to change the time format. If you want to switch from 12 - hour to 24 - hour format, press the "UP" button until "24H" is displayed. If you prefer the 12 - hour format, press the "DOWN" button until "12H" is shown.

Step 4: Exit the Setting Mode

After selecting the desired time format, press the "SET" button again to save the changes and exit the setting mode. The time display will stop flashing, indicating that the clock has returned to normal operation.

Troubleshooting

If you encounter any problems during the setting process, here are some tips:

  • Button Not Responsive: Check if the batteries are properly installed and have enough power. If the batteries are low, replace them with new ones.
  • Incorrect Display: If the time format doesn't seem to change correctly, try repeating the setting process from the beginning. Make sure you are pressing the buttons firmly and following the steps accurately.
