Subtract 2 date columns in .csv file and get output as number of days

Hi,

I need to calculate how many days exist between 2 dates.

I am trying to subtract date column 2 from date column 3.
Eg: my file look likes

s.no, Start_date,End_Date
Code:
1, 7/29/2012,10/27/2012
2, 7/29/2012,8/11/2012

my output should be
Code:
90
13

like this.

I am not able to get command to calculate how many days exist between these 2 dates.
after that, As i need to check how many sundays exists between the dates. so I will divide number of days/7.
Please help.

SYNOPSIS
string px_date2string (resource $pxdoc, int $value, string $format) DESCRIPTION
Turns a date as it stored in the paradox file into human readable format. Paradox dates are the number of days since 1.1.0000. This func- tion is just for convenience. It can be easily replaced by some math and the calendar functions as demonstrated in the example below. PARAMETERS
o $pxdoc - Resource identifier of the paradox database as returned by px_new(3). o $value - Value as stored in paradox database field of type PX_FIELD_DATE. o $format - String format similar to the format used by date(3). The placeholders support by this function is a subset of those supported by date(3) (Y, y, m, n, d, j, L). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Turn a paradox date into a human readable form <?php $px = px_new(); /* make up a date as it could be stored in */ /* a date field of a paradox db. */ /* 700000 days since 1.1.0000. */ $days = 700000; /* Use the calendar functions to print a */ /* human readable format of the date */ echo jdtogregorian($days+1721425)." "; /* px_date2string() outputs the same */ echo px_date2string($px, $days, "n/d/Y")." "; px_delete($px); ?> The above example will output: 7/15/1917 7/15/1917 SEE ALSO
