I'm using php date('W'); function to get a number of the week of this year.
date('W') says "40" (that's correct).
The problem is, that my Linux machine, CentOS has a correct date, but shows incorrect week number.
date +"%W" says "39"
Does anyone know why it works this way and how could I fix it?
Okay, I found the answer:
I need to use it like this: date +%V
%V ISO week number, with Monday as first day of week (01..53)
%W week number of year, with Monday as first day of week (00..53)
date('W');
The code above gives the ISO-8601 week number (don't know what Linux shows by default). If you want the correct year there as well, use
date('W o');
instead of (W Y), because the o gives the right year with the W-week.
