To count Sundays in a month in Excel, use the formula: `=NETWORKDAYS.INTL(DATE(year,month,1),DATE(year,month+1,0),"1111110")`. Replace `year` with the specific year and `month` with the month number (e.g., 1 for January). This formula utilizes the `NETWORKDAYS.INTL` function to count days excluding Saturdays and Sundays; however, by customizing the weekend parameter to "1111110", it counts only Sundays. Ensure to enclose the weekend parameter in quotation marks and modify the year and month placeholders accordingly.
