How To Get Thursdays Of Year Using Carbon - laravel-5.1

Question

I want to get all the Thursdays of a year using Carbon and save it on DB.
so far I could only store the Thursdays of current month. please advice me how to make it for the whole year once.
Current code :
public function getThursdays()
{
return new \DatePeriod(
Carbon::parse("first thursday of this month"),
CarbonInterval::week(),
Carbon::parse("first thursday of next month")
);
}
public function handle()
{
$thursdays = $this->getThursdays();
foreach ($thursdays as $thursday)
{
$Weeks = new Week();
$Weeks->week_starting_date = $thursday;
$Weeks->save();
}
}

Answer 1

You can get the number of weeks per year firstly using WEEKS_PER_YEAR, e.g :
$weeks_per_year = Carbon::WEEKS_PER_YEAR;
After that get the first thursday of year using :
$first_thursday = Carbon::parse("first thursday of this year");
Then loop through all the weeks adding every time one week using Carbon function addWeeks(1) to get the thursday of the next week and so :
for($i=1;$i<$weeks_per_year;$i++)
{
array_push( $thursdays, $first_thursday->addWeeks(1)->toDateString() );
}
FULL code :
$weeks_per_year = Carbon::WEEKS_PER_YEAR;
$first_thursday = Carbon::parse("first thursday of this year");
$thursdays = [$first_thursday->toDateString()];
for($i=1;$i<$weeks_per_year;$i++)
{
array_push( $thursdays, $first_thursday->addWeeks(1)->toDateString() );
}
Output :
An array of all the year thursdays in following format yyyy-mm-dd :
["2016-01-07","2016-01-14","2016-01-21", ... ,"2016-12-29"]
Or you can store dates directely in you DB instead of returning an array like :
for($i=1; $i<$weeks_per_year;$i++){
$Weeks = new Week();
$Weeks->week_starting_date = $first_thursday->addWeeks(1)->toDateString();
$Weeks->save();
}
Hope this helps.
