Hello!

I searched and puzzled myself but without any luck so i hope somebody can help me with this: 

I want a formula or some other way to calculate the weeknumber from a given date in infopath.

So a user selects a date in a datepicker and then a formula calculates the weeknumber. (week is 7 days, beginning in January ending in December)
The form is browser enabled so i cannot use code.

I read some articles and posts about calculating dates from weeknumbers but i want the other way around.

I hope somebody can help me with this!

Any ideas are much appreciated!

Kind regards,

Bram

I see no problem to calculate weeknumber by applying same principles as in that article:

 the week number will be amount of days since the beginning of the first week of the year divided by 7 and rounded to the largest integer.

Thanks Alec!
This was exaclty where i was looking for!

Kind Regards,

Bram
