@uk_a try

.yui3-squarespacecalendar .sunday:first-child

@tuanphan

Thank u. However, it could not be solved.

Is the description incorrect?

 .yui3-squarespacecalendar .sunday:first-child{ color: #ffffff !important; background: #b3b3b3 !important; }

@uk_a try these

.yui3-squarespacecalendar .yui3-calendar-row:first-child .sunday {
   background: #b3b3b3 !important;
   color: #fff !important;
}

@tuanphan Thank you!

Great!!

Sunday in the first week was changed.

However, my way of communicating was bad. I'm sorry.

Do you have a solution if there is no Sunday in the first week and the second Sunday is the first Sunday of the month?

I want to change the color only on the first Sunday in the month.

Thank you for your consideration.

@uk_a That was the problem I was thinking, before sending the above code. Seems difficult. Still thinking.

My friend suggested using JS / jquery to handle. However it's beyond my ability.

There is a temporary workaround. If you have 12 months, you will manually insert the code to handle the above problem (will need about 2-9 code as above)

When 2020, 2021 ... comes, you will continue to change the above code, so that it works with the new year.

Thank you for your efforts.If you find a solution in the future, please contact me.

If you know how to specify the month and year, please let me know.
