Yeah, I would definitely suggest a table like that over the countdown idea.
The equivalent of that table for your variable frequency would be this:
```dataview
TABLE WITHOUT ID file.link AS work, updated + frequency AS "planned update"
FROM "your/folder/path"
WHERE dur(frequency) AND (updated + frequency <= date(today))
```
(Change your/folder/path to your folder’s path.)
You might already know, but just making sure: Use valid natural language for your frequency, such as “2 days” or “3 months”. (Explained here).
(edit to add…)
And if you wanted to see all your works in order of when the next update is, then you could do something like this:
```dataview
TABLE WITHOUT ID file.link AS work,
updated,
frequency,
updated + frequency AS "planned update"
FROM "bookshelf-folder"
WHERE dur(frequency)
SORT updated + frequency ASC
```
Just wanted to put this second table here to hopefully make it easier for you to think about your options and adjust it how you want.
