Shark week is in the month of August. Shark week falls on a Sunday.
Your fish will be much happier if you change at least 50% of the tank water every week.
About once every month.
Then it's a month-to-month (or week to week) tenancy.
December of 2012 is a five week month.
One week is seven days. Depending on which month you use, if one month is 30 days, then one week would be 7/30 of a month.
The first of the month can fall on any day of the week.
You can. I changed mine after a week and a bit and they are perfectly fine a month later.

I always thought the last week was the one fully enclosed in the month. Although I suppose it could be just explained as either the last full week or the last week of one month/ beginning of the next.....Example: The last full week of July or the last week of July-beginning of August. If it's always explained the confusion is avoided. Everyone has their own opinion of what the last week of the month is.
