Base is not a database. Base is a tool to work with variuos types of

talking about an embedded HSQLDB then all I can tell is, that there is
no built-in way to calculate dates other than CURRENT_DATE. "Better"
databases have a function DATEADD at least.
Which type of database are you connected to?
This might not be the most elegant solution:
I created a table of dates (01/01/2012 to 12/31/2013) calling it "Date".
Then I wrote a query using the following SQL:
SELECT "Date" FROM "Date" WHERE DATEDIFF('dd',:start_date,"Date")
=180 OR DATEDIFF('dd',:start_date,"Date") = 365
:start_date is a parameter. When the query is run, a dialog asks you for
the start date. It then returns the date 180 days later followed by the
date 365 days later.
Does someone know how to create a table using SQL or perhaps even a
macro that would create the date table with enough entries for the
number of years that this database might need?
