If you want the DAY before, you can use the -1 for the day, and get
what you want.
mktime() will "wrap" the month as needed.
But, yeah, if you try to hit a MONTH before by putting in a month
before AND the day, it will "slingshot" back and forth to get what you
don't want.
If you want the MONTH before, I *suspect* you can use date('m') for
the argument, and do NOT provide a day, and it may do what you want.
But for sure, if you use ONE (1) for the day, and then -1 for the
month it will do what you want, since every month has a ONE (1) day.
Anything 1 from 28 will work fine, actually, but using 1 is probably
clearest:
$today = mktime();
$tomorrow = mktime(1, 0, 0, date('m'), date('d') + 1);
$next_month = mktime(1, 0, 0, date('m') + 1, 1);
$last_month = mktime(1, 0, 0, date('m') - 1, 1);
I've been using these for a web calendar since nineteen-ninety-mumble,
and they've worked fine, through leap years.

The HTML version has the exact same stuff at the top.

Feel free to page through as many months/years past/present and future
to see that it works.
Since it's a 32-bit machine, it does conk out in March 2038.
I'm fairly confident our web-server will be a 64-bit machine before we
book any (real) events for 2038...
You can ignore my test events in January 2038 :-)
