How often per day do we have an update?

The database contains 399,868 bills totalling $ 6,718,143.
Can't wait to see number 400,000 entered!

I believe it is whenever you go to the home page it is calculated for you.

It's at 399,876 for me so the 400,000 mark should be made tonight or maybe tomorrow morning.

Thanks kaybee I will stay posted to check this one out if it comes tonight!
