# Thread: Date and Time issues

1. ## Date and Time issues

Hey all,

Okay, I have a problem -
I have links from MONDAY to FRIDAY... and when the user clicks on the link it will send the script a value of 1-5

1 through 5 equals mon,tue,wed,thr,fri...

Now my problem is I need to take that 1-5 and convert it to the DAY its on.

Meaning, today is Saturday(23rd) if they click Monday(Happends to be xmas) it woudl show the date 25th.

Anybody know how I can do this? or a better way to do it?

• Here is some code to do this (tested) -
PHP Code:
``` <?php \$today_day_number = date("w"); echo "Today's day of the week is: \$today_day_number (0=Sun, 1=Mon...)"; echo "<br />"; // test loop for possible values 1-5 // \$test_value is simulating the value received as input from the form for(\$test_value=1; \$test_value <=5;\$test_value++){     // if today_day_number is 6 (sat) - make this -1 so difference math works     if(\$today_day_number == 6)     {     \$today_day_number = -1;     }     // if test value (1-5) is greater than or equal to today_day_number, then test value is today or higher (coming week or current week)     // if test value (1-5) is less than today_day_number, day entered has already gone past and is actually the following week (add 7)     if(\$test_value >= \$today_day_number)     {     \$difference = \$test_value-\$today_day_number;     } else {     \$difference = \$test_value-\$today_day_number+7;     }     echo "Test value: \$test_value, Difference: \$difference, date: ";     echo date("d",mktime(0, 0, 0, date("m")  , date("d")+\$difference, date("Y"))); // mktime correctly does the math and wraps to the next week/month/year as needed     echo "<br />"; } // end of test loop for possible values 1-5 ?> ```
I actually tested this within another loop to simulate all the possible values for \$today_day_number (0-6) and it looks like it works correctly.
