explain this mktime "anomalie" to me please

[scrupul0us]

why does:

$colum  = date("n j",strtotime("second monday",		mktime(0,0,0,10,0,$year)));
//gives second monday

differ from:

$colum  = date("n j",strtotime("second monday",		mktime(0,0,0,10,1,$year)));
//gives third monday

Why would setting the day to ZERO render the correct date (columbus day is the second monday in october)... ive always coded using a "1"... should i go back and check over things?

10/1/2007 is a Monday, so "second monday" from then is the 3rd Monday of this month. When you use 0 for the day in mktime(), it is interpreted as the last day of the preceding month, making your "second monday" expression return the desired result).

[scrupul0us]

so in general then, when using that style of coding i should specify "0" for the day

its the little details like that i wish were in the php manual

heres another:

$memday = date("n j",strtotime("last monday",		mktime(0,0,0,5,0,$year)));

for this year it would have been May 28

however the output of the above code is: "4 23" or April 23rd

what am i doing wrong there? i want the last Monday in May, but instead its giving me the previous monday prior to May

"Last monday" does not mean "the last monday of the month" in this context, but rather as you might use it in conversation, such as, "I was sick last Monday so stayed home that day." But you can use it to get the last day of a month by setting the time to the first day of the next month:

$lastMondayOfOctober = strtotime('last monday', mktime(0,0,0,11,1,2007));
