Automatically Input Date Every Week

I have a chart using Chart JS and The Labels is Monday, Tuesday, Wednesday, Thursday, Friday

and then this is my code

    <?php foreach($connect->query(
    "SELECT Process_Date, 
    COUNT(*) 
    FROM tb_main 
    WHERE DATE(Process_Date) = '2022-03-28 00:00:00' 
    GROUP BY Process_Date 
    LIMIT 1") as $row) {
    echo $row['COUNT(*)'];}?>,

this code is repeated 5 times (to fill data every day).

I want to change that (‘2022-03-28 00:00:00’) Automatically every week. Example :
This week Monday until Friday is 2022-03-28 – 2022-04-01. and then the next week is automatically change to 2022-04-04 – 2022-04-08.
is it Possible?
