In this page you will find a comprehensive list of digital clock format strings you may use when changing the display settings for the desktop digital clock on your Raspberry Pi computer.
Each digital clock format string is an upper or lowercase character preceded by the percent sign. Characters not preceded by the percent sign are displayed as entered. The (%%) format string allows for the literal percent (%) character to be displayed. Literal characters may be placed within the digital clock format strings.
Note: Please visit link below for how to change your desktop clock.
Many people prefer a 12-hour clock, and because the desktop clock typically displays a 24-hour clock, one popular digital clock format is shown below:
As a result of using this clock format string, if the Time were 9:21 am in the morning the desktop clock would display:

The Raspberry Pi desktop clock by default usually shows only the time in a 24-hour clock format. Using this list of format strings you now have the power to display the date and time however you would like. Right click on the Raspberry Pi Desktop Clock and select Digital Clock Settings from the popup menu. Modify the Clock Format text field as desired for your new desktop clock.
This list of clock format strings was compiled from the manual page for “strftime“. To view the manual page, open the Raspberry Pi Terminal from the desktop type the following command:
