Shall be much obliged if you would elaborate as to what you mean by extracting date from a DateTime field in Access 2000.
There are far number of options which allows you to extract a date or a range of dates based on the date field itself and/or respective field values.
There is also a question of how you would like to use the extracted date(s). In other words, you could display the extracted date(s) on a text box, label, list box, combo box - all these on a form, and/or write them to a (temporary) table or use them with another query, and/or display them on a report. The options are endless.
For obtaining a quick and methodical solution from the newsgroup, I would suggest that you post a sample data of the table.
