showISOWeekNumbers usage

[andcmill]

Hi I am using your daterangepicker. It's a great tool. I began to use the showISOWeekNumbers as true. It's returning a week number which does not match the EPOCH Converter ISO week number. Is this a bug or am I misapplying the tool set?

You should also set locale: { firstDay: 1 } in your settings so that weeks start on Mondays in the calendar. Then the ISO week numbers will make sense, as those also start on Mondays.

@dangrossman Thank you for the hint! This worked perfectly and now makes sense. It's been part of our project for a long time now. Thank you for developing it.

showISOWeekNumbers: true,
locale" { firstDay: 1, weekLabel: "ISO" },
