I have a circumstance where I need to calculate counts based on
user set start times, end times, and intervals. It looks like the
partition function (http://office.microsoft.com/en-us/access/
HA012288921033.aspx) would do exactly that but it requires whole
numbers not dates. SO......
1) Is there a partition function based on dates?
2) Is there a way to convert dates to numbers to use the function?
3) Is there another way to get the same sort of effect as the
partition function?
Dates or date/times?

date/times are stored in Access tables as the number of days since
December 31st, 1899, with the time as a fraction of a day.
You could therefore convert today to a long integer using
clng(date()) which is day 40281
You could alternatively use several of the date functions to get the
specified interval I regularly run a totals query by month using the
datepart("yyyy",[dt_created])*100+datepart("ww",[dt_created]) in a
totals query to return the count of records added each week
