I am trying to get weekend date of 17-03-2021
Currently in am getting weekend date of current week i want to get by specific date.
Carbon::now()->endOfWeek()->format('d-m-Y')
If Carbon::now()->endOfWeek()->format('d-m-Y')
is doing what you want, just not with a specific date, then parse the date you want to base this from:
Carbon::parse('17-03-2021')->endOfWeek()->format('d-m-Y')
Also consider ->nextWeekendDay()
and ->previousWeekendDay()
as ways to access the weekend.
