Nice

Little brother is stupid, how to input a number in seconds, and the output only needs to be accurate to seconds. And the code is in a batch file.

What does "call :clc !h! " mean?

Just look at call /? and setlocal /?

@echo off
setlocal enabledelayedexpansion
set /p Input=Enter seconds:
if %Input% GTR 0 set /a Y=%Input%/31536000&set /a D=(Input%%31536000)/86400&set /a H=(Input%%86400)/3600&set /a M=(Input%%3600)/60&set /a S=Input%%60
echo Equivalent to: %Y% years %D% days %H% hours %M% minutes %S% seconds.
pause>nul

Overflow will occur if the years exceed

@echo off
setlocal enabledelayedexpansion
set /p Input=Enter seconds:
if %Input% GTR 0 set /a Y=%Input%/604800&set /a D=(Input%%604800)/86400&set /a H=(Input%%86400)/3600&set /a M=

(Input%%3600)/60&set /a S=Input%%60
echo Equivalent to: %Y% weeks %D% days %H% hours %M% minutes %S% seconds.
