This is probably the simplest indicator I have ever made.
It just gives you a the days of weeks in your specified time zone and puts the day on the first bar in your time zone.
You can use UTC time format or named time zones like the default.
Just for fun I tried to give it symbols that sort of relate the old gods that the days of week were named after and even colors that one could argue match, but it was all in fun because it was so simple I felt I had to add something.
Enjoy.
