Magento Report: Find out number of orders per day

Today I was curious to find out about the days where most of the orders were placed.

If you want to find out about the same, use this SQL query:

SELECT COUNT(*) as orders_per_day, date(created_at) as day
FROM sales_flat_order
GROUP BY date(created_at)
ORDER BY orders_per_day DESC
