You should not separate data by years. Rather, use a date field in the
table. Create a query based on the table. In the criteria for the date
field:
Between [Enter start date] And [Enter end date]
There are a lot of ways to go about using criteria. This is just one of
many options. You can use the current year automatically, or you can just
enter the year rather than a date range. It's depends on how you specify
the criteria.
You can add the data automatically when you enter a new record. Set the
Default Value of a text box bound to a date field to:
=Now()
Default Value affects only new records.
Use a query to sort by that field to see records in the order they were
entered.
