You must not do that. This is how one would work with paper records.
A spreadsheet can store thousands of rows in arbitrary order and the
software lets you pull out the sum, average, deviation, min, max for
every month, year, week, day and all other categories in a clean and
comparable manner.
The "Data" menu covers database-like tasks.
Pivot tables (aka data pilots) are the most convenient way to aggregate
data records by categories and times.
