Which version of Obsidian / dataview are you using? It seems like a rather old variant since you’re still using luxon… Oh well…
Try the following:
Now as an ISO Date: `$= dv.date("now").toFormat("yyyy-MM-dd")`
Updated version of yours: `$= dv.fileLink("Reviews/00 Dagen/" + dv.date("now").toFormat("yyyy-MM-dd"), false, "Review van Vandaag") `
Which produces this for me:
There are also options to use moment() within dataviewjs, but I find it a little confusing, as then all the momentjs date tokens are used, whilst when using dateformat and this toFormat the luxon date tokens are used. They are mostly the same, but there are differences, which I find a little confusing.
