Laravel 5.1: Fetching rows added last hour

I am working on a project, in which i have to track all the records which are added in last hour of current time.

I am able to do this by using following query,

select count(*) as cnt
from  log
where date >= DATE_SUB(NOW(),INTERVAL 1 HOUR); 

but not able to do the same in Laravel.

Please help me to sort out this issue.
