Establish a free accounting date report _access

Microsoft Access reports provide statistics grouped by date, but only for full years, months, days, and so on, that is to say one months of data must be from the beginning of the month to the end of the month. We write programs, there are many statistical systems in the work, and the units of the statistics are based on the accounting date, the accounting date is not necessarily from 1st to 31st, and some companies from the last month of 26th to this month's 25th counted one months, so that the Report Wizard automatically generated by Access report will not be. Of course, or we do it ourselves, in fact, very simple, a learning will. 1. Recognize several functions related to time 2. Create a form that lets users select a date 3. Automatically calculates beginning and end dates 4 based on the date selected by the user. Let the report process the data between the beginning and the end of the period
