LIbreOffice base set variable and use with multiple forms and reports

LO, HSQLDB, MacOS Mojave 10.14.6


I have a LO base database that uses dates as criteria for a lot of the forms and queries, at the moment each time one of those forms or reports is run the user is required and prompted to input the date, however the date which is input remains the same for 8 days so it would be great if it was possible to set this date once and it be held / stored for use in all form or report functions for the 8 days (unless manually) changed to another date which would then be used from then on until changed


Create a single record table with a ID and a date field. Store your date there and use that for your queries. This is quite common in filtering techniques.
