Ubuntu 16.04 LTS: First weekday set incorrectly in the stock Calendar app (gnome-calendar, ver. 3.20.1)

[w1ssrukte9uoe7160yx5i5iz6jnqo0ka]

I use Ubuntu 16.04 (LTS) with the stock Calendar app (Gnome-calendar, ver. 3.20.1). My system language is en_US however my regional is fi_FI.

The Gnome Calendar Shell is showing the first day of the week as a monday (which is correct in this region) however the stock calendar app is still showing Sunday.

Here's my exact locale settings:
LANG=en_US.UTF-8
LANGUAGE=en_US
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC=fi_FI.UTF-8
LC_TIME=fi_FI.UTF-8
LC_COLLATE="en_US.UTF-8"
LC_MONETARY=fi_FI.UTF-8
LC_MESSAGES="en_US.UTF-8"
LC_PAPER=fi_FI.UTF-8
LC_NAME=fi_FI.UTF-8
LC_ADDRESS=fi_FI.UTF-8
LC_TELEPHONE=fi_FI.UTF-8
LC_MEASUREMENT=fi_FI.UTF-8
LC_IDENTIFICATION=fi_FI.UTF-8
LC_ALL=

I've tried changing my "/usr/share/i18n/locales/en_US" values into this as a root user:

week 7;19971130;4
first_weekday 2
first_workday 2

the fi_FI is following:

week 7;19971130;4
first_weekday 2 % Monday
first_workday 2 % Monday

Then I did 'sudo locale-gen' and reboot the PC but it's still showing sunday as a first day of the week on the stock Calendar app.

Thanks, that's a known upstream issue, see https://bugzilla.gnome.org/show_bug.cgi?id=762428

The bug has been fixed upstream with https://git.gnome.org/browse/gnome-calendar/commit/?id=5e05f998761c669e3e995051d658268b3d8e3a0d

the change should be in the next ubuntu update/SRU

Yes. 3.20.2 has the fix.
