Week 1 of 2015 (2015W01 in ISO notation) started on Monday, 29 December 2014 and ended on Sunday, 4 January 2015, because 1 January 2015 fell on Thursday. Here is an example: $date = strtotime('') Įcho date("W o", $date) // output: 53 2015 ![]() However, we need 2015, because from the point of view of the calendar week, January, 1 is belonging to the last week of the last year in this case.įortunately, the developers of PHP have thought of this special case and bestowed the parameter "o" (lowercase O) upon us. If we use this parameter instead of the usual parameter Y for the year with the date() function, we will receive the year suitable for the passed date's week number. 2015 starts on Thursday, January 1st 2015 and ends on Thursday, December 31st 2015. The reason for that wrong result is that "Y" is providing us the year of the passed date - this is 2016. The year 2015s maximum week number is WN 53. This example shows, what is going wrong: For the date, we get the week number 53 of 2016. In both of this cases, the usage of date("W Y", $date) leads to wrong results: $date = strtotime('') Įcho date("W Y", $date) // output: 53 2016 The problem can occur whenever the first calendar week of the new year is already starting in December or if the last calendar week of a year is going over into January. There is one problem that arises almost at each turn of the year. For example, with a Monday-to-Sunday week. With this, the result of the function is converted from a string to an integer number whose output is naturally single-digit without any leading zeros. The required number of days in the week containing the first day of the calendar year to make that day part of week 1. If we want to have a single digit number for the week numbers 1 to 9, we can just write (int)date("W", $date) to get it. Here is an example for this call: $date = time() // current dateĮcho date("W", $date) // output, for example: 03 or 10Īccording to ISO-8601, for PHP, the week begins at Monday and the output is formatted in the form of two digits as string.
