This might help you You could actually just the INTEGER type here, except that the column would store the number of half days. To find out how many total complete days there were, you would have to divide by two (which, according to your rules, would either yield a whole number, or a whole number with a fractional component of 0.5).

MySql Query: include days that have COUNT(id) == 0 but only in the last 30 days

I wish this help you You need a table of dates, then left join to the builds table.
Something like this:
code :
SELECT 
    COUNT(id) AS 'Past-Month-Builds', 
    CONCAT(MONTH(DateTable.Date), '-', DAY(DateTable.Date)) as 'Month-Day' 
FROM DateTable
    LEFT JOIN builds ON DATE(builds.submittime) = DateTable.Date
WHERE DateTable.Date >= DATE_SUB(CURDATE(), INTERVAL 30 day) 
GROUP BY MONTH(submittime), DAY(submittime);

Loop through 2 dates and execute a condition each 12 days, 2 days, 12 days, 2 days, etc

may help you . You can consider a period to be 14 days long, which could be split in two subperiods - first of 12 days and the second of 2 days.
So each step of your loop could process 14 days:
code :
$periodStartAt = 0;
while(true) {
    $periodStartAt += 12; // first sub-period
    if ($periodStartAt > $endAt) break;
    //do something when first sub-period reached

    $periodStartAt += 2; //second sub-period 
    if ($periodStartAt > $endAt) break;
    //do something when second sub-period reached
}

How to generate a count of data for a particular dept for a specific days (3days, 4-7 days, 15 - 30 days) by using excel

should help you out If I understand you correctly, you want to return a period name (e.g. <3 Days, 4-7 Days, or 8-14 Days, etc.) in Column D based on the Days Count.
If so, you can use the approximate match of VLOOKUP to achieve that, but you will need to create a look up table first. See below screen-shot for details. Please note I have named the look up table as Tbl_Period in my solution.

it fixes the issue You can use Comparator.comparingInt which required a function to extract an int from your object, in this case a String:
code :
list.sort(Comparator.comparingInt(s -> Integer.valueOf(s.split(" ")[0])));
