I have a question. In WIN2003, to create a folder with the current date, you can use
md %date% to create it.
How should I write a batch file to create a folder with the next day's date? Thanks.

Using datex to calculate dates is very convenient

datex???
What is that???
I've been lurking too long ` don't understand

Search the forum.
A command-line tool for date calculation

No tools, just built-in system commands, okay?

Yes, but I definitely don't know how. There are already many examples on the forum for calculating time and dates.
Search for them yourself

I'm also looking forward to the day when some expert starts a thread explaining in detail how to calculate time and dates and all that

I already searched, and there isn't a similar solution. Calling on the moderators to lend a hand!

Using datex is such a perfect thing
@echo off datex -f yyyy年MM月DD日 -o 1>d.txt set /p d=<d.txt echo %d% md %d% pause

Posting the description of the VBS DateAdd function




DateAdd(interval, number, date)
Arguments
interval
Required. A string expression that specifies the time interval to add. For values, see the "Settings" section.
number
Required. A numeric expression that specifies the number of time intervals to add. The numeric expression can be positive (to get a future date) or negative (to get a past date).
date
Required. A Variant or date literal representing the date to which interval is added.
Settings
The interval argument can have the following values:

Setting Description
yyyy Year
q Quarter
m Month
y Day of year
d Day
w Weekday
ww Week
h Hour
n Minute
s Second

Description
You can use the DateAdd function to add or subtract a specified time interval from a date. For example, you can use DateAdd to calculate the date 30 days from today, or the time 45 minutes from now. To add a time interval in units of "days" to date, you can use "day of year" ("y"), "day" ("d"), or "weekday" ("w").

The DateAdd function does not return an invalid date. In the following example, one month is added to January 31, 1995:

NewDate = DateAdd("m", 1, "31-Jan-95")
In this example, DateAdd returns February 28, 1995, rather than February 31, 1995. If date is January 31, 1996, it returns February 29, 1996, because 1996 is a leap year.

If the calculated date is earlier than the year 100 AD, an error occurs.

If number is not a Long value, it is rounded to the nearest integer before calculation.

@echo off
echo Wscript.echo dateadd("d",1,date)>vbs.vbs
for /f %%d in ('cscript //nologo vbs.vbs') do echo %%d&&md %%d
pause

This code tested successfully on my 2003 system

There is a method for calculating date and time in the batch function library

Anything that's not code you wrote yourself is really hard to understand

If you want to directly use its function to calculate tomorrow's date, does that mean converting the date to a day count, then adding 1, then converting it back to a date?
