If I enter a letter, it still appears:

Please enter the number of seconds: dddd

0 days 0 hours 0 minutes 0 seconds

Press any key to continue...

Am I here to cause trouble,,, hehehe... ;)

Understand the above code as (not milliseconds):

set /a D=%t%/86400
set /a H=%t%%%86400/3600
set /a M=%t%%%86400%%3600/60
set /a S=%t%%%86400%%3600%%60
ECHO %D% days %H% hours %M% minutes %S% seconds

The perception is: The value is t divided by 86400 seconds (equal to 1 day), the quotient is the number of days, the remainder is divided by 3600 seconds (equal to 1 hour), the quotient is the number of hours, and the remainder is cycled again, and so on, which can be extended to weeks, months, and years. But due to the 32-bit precision limit, it will not achieve the maximum expected effect

Thanks for pointing it out, hehe. It was written carelessly. It has been corrected.

You guys are amazing. You even got the milliseconds accurate. It seems it can be modified into a Spring Festival countdown^^

Is there a way to break through the 11-day limit? If the number is too large, it will overflow. Thanks!

Look at this!! :)

Your algorithm is very good, I am stupid. How to input a number in seconds and output it with precision to seconds only. And the code is in a batch file.

Can you write it out, thank you very much!
