Answer 1

you can use the date_sub function from mysql

get all records from last week

SELECT count(doctor_name) AS totalleads FROM `wp-leads-count` WHERE doctor_name ='Sasanthi' and leads_date between date_sub(now(),INTERVAL 1 WEEK) and now()

get all records from last month

SELECT count(doctor_name) AS totalleads FROM `wp-leads-count` WHERE doctor_name ='Sasanthi' and leads_date between date_sub(now(),INTERVAL 1 MONTH) and now()

Answer 2

try

$daynumber = date('N', date('d'));// getting today day number
$prevweek = $daynumber+7; // starting from prev week 
echo $prevdate = strtotime('-'.$prevweek.' days'); // prev week date
echo strtotime("-1 month"); // last month
