You can add a reminder function, such as reminding what to do when a certain time comes. Due to my time constraints, I posted in a hurry, please bear with me and put forward valuable opinions. The purpose of each of my posts is to focus on the theme of common improvement. The code is as follows:
@echo off
:begin
mode con cols=40 lines=3&setlocal EnableDelayedExpansion
title dos clock
set /a a=%random%/3640&set /a b=%random%/3640
cls&color %a%%b%&echo.&echo.&echo.&echo 　　　%date% !time:~-11,-3!&ping/n 2 127.1 >nul
goto begin

Added reminder function and modified error codes:
@echo off&setlocal EnableDelayedExpansion
:begin
mode con cols=40 lines=3
title dos clock
set t=!time:~-11,-6!
if "%t%"=="18:00" goto show
set /a a=%random%/3640&set /a b=%random%/3640
cls&color %a%%b%&echo.&echo.&echo.&echo 　　　%date% !time:~-11,-3!&ping/n 2 127.1 >nul
goto begin
:show
cls&color 9f&echo.&echo.&echo.&echo 　　　It's time to get off work!
goto begin

The building owner is really cute, I guess it's a girl (I have no bad intentions)

Only after checking the information did I realize the original poster is a handsome guy. Sorry about that. The post has great ideas, so I'll give a thumbs up here.

Tested it, and the effect is pretty good

Spent two hours thinking I understood the %var:~1,5% usage of set, but how to understand
=!time:~-11,-6!
For example, the result of entering the time command is:
18:20:55.75
How to intercept it?

set t=!time:~-11,-6! can be changed to set t=!time! directly

Actually, the system time is composed of 11 characters. The command!time:~-11,-6! means to intercept 11 characters from the time starting from the back and discard 6 characters from the back. For 18:20:55.75, the intercepted characters are 18:20. It seems you are not very familiar with the character interception command. Here is a practice tool for you: http://www.cn-dos.net/forum/viewthread.php?tid=38251&fpage=4, I believe you will be familiar with it in a short time.

Different understanding, but this tool is not enough to enhance my understanding because there are no negative numbers
I don't know if my understanding is correct, but I still think this understanding is fast. For example, you said
%var:~5,5%
Intercept 5 from the front and 5 from the back
My understanding is
Start from the 6th character, intercept 5 and assign to the variable, no matter right or wrong, but it is very clear

@echo off&setlocal EnableDelayedExpansion
:begin
mode con cols=40 lines=3
title dos clock
set t=!time:~-11,-6!
if "%t%"=="12:00" goto show
if "%t%"=="18:00" goto show
set /a a=%random%/2184&set /a b=%random%/2184
if "%a%"=="15" set a=f
if "%a%"=="14" set a=e
if "%a%"=="13" set a=d
if "%a%"=="12" set a=c
if "%a%"=="11" set a=b
if "%a%"=="10" set a=a
if "%b%"=="15" set b=f
if "%b%"=="14" set b=e
if "%b%"=="13" set b=d
if "%b%"=="12" set b=c
if "%b%"=="11" set b=b
if "%b%"=="10" set b=a
cls&color %a%%b%&echo.&echo.&echo.&echo 　　　%date% !time:~-11,-3!&ping/n 2 127.1 >nul
goto begin
:show
cls&color 9f&echo.&echo.&echo.&echo 　　　It's time to get off work!
goto begin

Not bad!
Can be strengthened a bit more. Add sound prompt.
Use bell to ring (enter ctrl+g in cmd)
Or call mshta
mshta vbscript:createobject("sapi.spvoice").speak("time is go home.")(window.close)

@echo off&setlocal EnableDelayedExpansion :begin mode con cols=40 lines=3 title dos时钟 set t=!time:~-11,-6! if "%t%"=="12:00" goto show if "%t%"=="18:00" goto show set /a a=%random%/2184&set /a b=%random%/2184 if "%a%"=="15" set a=f if "%a%"=="14" set a=e if "%a%"=="13" set a=d if "%a%"=="12" set a=c if "%a%"=="11" set a=b if "%a%"=="10" set a=a if "%b%"=="15" set b=f if "%b%"=="14" set b=e if "%b%"=="13" set b=d if "%b%"=="12" set b=c if "%b%"=="11" set b=b if "%b%"=="10" set b=a cls&color %a%%b%&echo.&echo.&echo.&echo 　　　%date% !time:~-11,-3!&ping/n 2 127.1 >nul goto begin :show cls&color 9f&echo.&echo.&echo.&echo 　　　下班时间到了！ mshta vbscript:createobject("sapi.spvoice").speak("time is go home")(window.close) goto begin

Learning mshta vbscript:createobject("sapi.spvoice").speak("time is go home")(window.close)
This is pretty good

Here is the translation of the provided content:

Here is a VBS script that can speak both Chinese and English.
Set objVoice = CreateObject("SAPI.SpVoice")
Set objVoice.Voice = objVoice.GetVoices("Name=Microsoft Mary").Item(0)
objVoice.Speak "Hi, this is Microsoft Mary"
Wscript.Sleep 2000
Set objVoice.Voice = objVoice.GetVoices("Name=Microsoft Simplified Chinese").Item(0)
objVoice.Speak "Hello, today is Sunday Hi, this is Microsoft Mary"
