month name from week number

[tkm]

Hello Mates,

  I am using the following function to get the month name from week number of a year.

date( "M", strtotime( "+$wk_no week", mktime(0, 0, 0, 1, 1, 2008) ) )

 

But what happens when the week extends to 2 different months ? Can anyone help me with any insights or suggestions ? Thank you.

That code gives you the first day of that week. You then add another 6 days to get the last day of the week, and then get the month name again. If they are different, you know the week spans two months.

 

Alternatively, you could see if the day of month + 6 is more than the number of days in the month. That way you can delay working out the month name a second time, in case you don't need to. But it's probably not a real performance issue, anyway.

Remember that January 1 is not always in the "first week" of the year.  it can fall in the 52nd week.

 

BUT January 4th is ALWAYS in the first week of the year.
