KOrganizer rightly sets Monday as the first day of the week. Calendar widget on the other hand sets Sunday as the first day of the week. When ever I have used LANG=en_IN.UTF-8 as my locale Monday is set as the first day of the week. Calendar widget doesn't follow that. Reproducible: Always $ locale LANG=en_IN.UTF-8 LC_CTYPE="en_IN.UTF-8" LC_NUMERIC="en_IN.UTF-8" LC_TIME="en_IN.UTF-8" LC_COLLATE="en_IN.UTF-8" LC_MONETARY="en_IN.UTF-8" LC_MESSAGES="en_IN.UTF-8" LC_PAPER="en_IN.UTF-8" LC_NAME="en_IN.UTF-8" LC_ADDRESS="en_IN.UTF-8" LC_TELEPHONE="en_IN.UTF-8" LC_MEASUREMENT="en_IN.UTF-8" LC_IDENTIFICATION="en_IN.UTF-8" LC_ALL= $ locale -ck LC_TIME LC_TIME abday="Sun;Mon;Tue;Wed;Thu;Fri;Sat" day="Sunday;Monday;Tuesday;Wednesday;Thursday;Friday;Saturday" abmon="Jan;Feb;Mar;Apr;May;Jun;Jul;Aug;Sep;Oct;Nov;Dec" mon="January;February;March;April;May;June;July;August;September;October;November;December" am_pm="AM;PM" d_t_fmt="%A %d %B %Y %I:%M:%S %p %Z" d_fmt="%A %d %B %Y" t_fmt="%I:%M:%S %Z" t_fmt_ampm="%I:%M:%S %p %Z" era= era_year="" era_d_fmt="" alt_digits= era_d_t_fmt="" era_t_fmt="" time-era-num-entries=0 time-era-entries="S" week-ndays=7 week-1stday=19971130 week-1stweek=0 first_weekday=1 first_workday=2 cal_direction=1 timezone="" date_fmt="%a %b %e %H:%M:%S %Z %Y" time-codeset="UTF-8"
As you can see in your locale output, en_in uses Sunday as first day of week. Calendar follows locale settings.
Unfortunately Plasma provides no way to change locale settings. I am not familiar with how locale works so I am back to square one.
Right click on the clock -> Set time format. This is unfortunately the best we can do at the moment. There should be some extending changes coming to Qt, on which the system relies on, then it would be possible to have more fine-grained options for that.

This miss configuration still exists in openSUSE Leap 15.1. I had to change it manually as Sudhir.
