Week of year

Yes, you have to calculate the value though. It isn't that difficult. I can post code.

Hello TRAVIS.VITEK,

That would be very happy if you could give me an example.
So I an approach as it can be done.
Thank you very much for your efforts.

greeting
Heiko

Sent code via PM.

Hello TRAVIS.VITEK,

many thanks for the code.
The works perfectly and is perfect.
I would never have managed that so that to write.
I am more in PHP / MySQL and JavaScript on the go, since the reaction would have been a problem for me.

Thanks again for that.

I could really like a copy of this code too.

Thanks a lot in advance

Hi Travis i am interresting in the code too

Thank's

Why the conspiracy all of a sudden?

using Toybox.Time.Gregorian as Greg;
...
var dateInfo = Greg.info(Time.now(), Time.FORMAT_SHORT);
var dayInAYear = (Time.now().value() - Greg.moment({:year => dateInfo.year, :month => 1, :day => 1, :hour => 0, :minute => 0, :second => 0}).value()) / 86400;
Sys.println("today is "+ dayInAYear +"th day of the year, "+ (dayInAYear / 7 + 1) +"th week");
...


Is there something particular I'm missing?

This is a good starting point, but the weeknumber is not calculated correct.

It seems a bit complicated to calculate, especially for the years containing 53 weeks.

Anybody have a final and complete solution so I don't have to re-invent the wheel

Thanks in advance

Well, I never really did these calculations before since in Android Java there's always trustworthy Calendar.getInstance.get(Calendar. WEEK_OF_YEAR), but I do like to reinvent wheels if it seems interesting enough 8)) According to provided Wiki, and I must admit, that this info was new to me, I'd change my code to this (checked to compile and run in simulator):

...
Sys.println("today is "+ getWeekNumber(Time.now()) +"th week");
Sys.println("01.01.2016 belongs to "+ getWeekNumber(Greg.moment({:year => 2016, :month => 1, :day => 1, :hour => 0, :minute => 0, :second => 0})) +" week");
Sys.println("03.01.2016 belongs to "+ getWeekNumber(Greg.moment({:year => 2016, :month => 1, :day => 3, :hour => 0, :minute => 0, :second => 0})) +" week");
Sys.println("04.01.2016 belongs to "+ getWeekNumber(Greg.moment({:year => 2016, :month => 1, :day => 4, :hour => 0, :minute => 0, :second => 0})) +" week");
...
function getWeekNumber(moment) {
var dateInfo = Greg.info(moment, Time.FORMAT_SHORT);
var firstDayOfTheYear = Greg.moment({:year => dateInfo.year, :month => 1, :day => 1, :hour => 0, :minute => 0, :second => 0});
var dayInAYear = (moment.value() - firstDayOfTheYear.value()) / 86400;
var weekNumber = dayInAYear / 7;
var firstDayDoW = Greg.info(firstDayOfTheYear, Time.FORMAT_SHORT).day_of_week;
// var lastDayOfFirstWeek = 9 - firstDayDoW; //my bad: Friday = 6, Satudray = 7, Sunday = 1
var lastDayOfFirstWeek = (9 - firstDayDoW) % 7;
return weekNumber == 0 && (firstDayDoW == 1 || firstDayDoW >= 6) && dateInfo.day <= lastDayOfFirstWeek ?
getWeekNumber(Greg.moment({:year => dateInfo.year - 1, :month => 12, :day => 31, :hour => 0, :minute => 0, :second => 0})) :
(weekNumber + 1);
}
