Okay, I see myself that idea about all that hashes and "Data dd/mm/yyyy" tabbles is a bit specific and it will tear the conception into peaces.
But 😉 what about making some tabbles to have numeral suffixes-endings which can be used to combine or to make ranges when combining?
For example, I make Tabbles Year 2001, Year 2003, Year 2006, Year 2008 with a template Year ####, where Year is my own word, and #### is a wildcard for any integer 4 digits value. All of that helps system to manipulate with these tabbles using also mathematical operations >,< and creating ranges such as Year 2000-2007, which means, can you imagine , just a combination of the tabbles Year 2001 or Year 2003 or Year 2006. In GUI it can be implemented, for example, in the following manner: you right-click one of the tabbles Year XXXX and see there is a menu item "Use the field from Tabble", click there and get a new tabble (which can be temporal or normal) with and ability to make range or comparison operation (Year ####>2001, Year 2001-2004, 2005-2008, similar to the pages field in printing dialog), which looks like you type inside the template >#### or <#### or ####-####.
Also it can be implemented in a form of nested tabbles: Parent tabble Year and child pure digital tabbles 2001 etc. The main idea is to find the tabbles with values (which are made using wildcards or digit fields) with flexibility other than selecting one-by-one from rather high amount of tabbles.

About enumerations – this may be too complex to be neccessary at all, but I’ll explain. Using not only bare numbers as described before, but also literal values from a kind of table/list (obviously – days, months names, all the things in our life, that have strong sequence and own names rather than numbers).

😆 Don’t tell me, that you already have a solution for all of that

Good luck
