Sharepoint 2016 DatePicker Error on farm with English setup and Norwegian language pack RRS feed

  • Question

  • Hi.  I have a farm with six members; App, Front End, Dist Cache, Search, DB and Office.  These servers are 2016 with English. Regional settings on servers are (now, not all at install time) Norwegian with Norwegian (nb-no) date formats.  

    When creating tasks, in a list view, with English language of display all dates from date picker are selected in European date format and then are changed to "today" with no other errors. When doing the same in Norwegian, all dates selected with date picker change to "i dag" (meaning "today"). After a day they change to "i går" (yesterday) and as time goes on they will appropriately count "6 dager siden" (six days ago) etc. As time goes on and the task ages, the due date will then read correctly so it appears that the calculating of a date as stored in the DB is working just fine. 

    Using the same date picker entering a task in the more complex mode which allows start date and end dates, in either language of display, gives a date error.   "You must specify a valid date within the range of 01.01.1900 and 31.12.8900." Manual dates entered in any format imaginable don't work. 

    When I enter a deliverable using the same datepicker all dates are fine.  

    My regional settings are:

    Timezone: +1

    Locale: Norwegian

    Sort Order; Danish/Norwegian

    Calendar: Gregiorian (tested with and without week numbers in the date navigator) 

    Alternate Calendar: None

    Week Definition: Tested with several options

    Timeformat: Tested with both 12 & 24, and remaining on 24.  

    From my perspective this looks like a customization error from something that was developed by a vendor, but I can be certain because I don't know where to go further with troubleshooting this.  Any ideas are appreciated!

  • Hi,

    If I understand correctly, in the same site in your environment, different task lists make different results. One gives a date error one works fine, am I right?

    Does the problematical task list have any customizations? How was this task list created? By OOB way? Could you provide a screenshot about this issue in the problematical task list?

    I have tested in my environment and it works fine, shown as figure below.

    Best Regards,

    Dean Wang

  • Hello, no update on the problem. I've tried to update language packs (jan-2017), but did not fix it. Here's a video of our problem:!AkLVDE9AnOnAkPcJhpwf_ZV_XrOaHw

  • Got it working, not 100% correct, but it is working for us Norwegians atleast. It may also apply to other Languages.

    I changed the region settings, from "Norwegian Bokmål" on the National settings, to "Norwegian nynorsk"
    - this only applies on how dates, time and numbers are shown, and Our two Languages are the same in that area.

    The datepicker now works as intended.

  • CU Jan 2018 doesn't fix the problem. Microsoft is investigating further.

  • On Finnish language we have now different error after CU Jan 2018.

    Error is : Index was outside the bounds of the array.

    But still not working.

  • SharePoint 2016 CU March 2018 fixes the timeseparator issue with DatePicker!

    When you use Norwegian (Bokmål) or any other locale that has the same separator for dates and times in Windows 2016, you receive the following error message when you verify the date and time fields:

    index was outside the bounds of the array
