I create a date with Luxon in the following way:

const date = DateTime.utc(2000, 6, 23).toFormat('yyyy-MM-dd')

Then I try to convert it to a JS date by doing this:

const jsDate = new Date(date)

Finally, I convert it back to the 'yyyy-MM-dd' format with

const parsedDate = DateTime.fromJSDate(jsDate).toFormat('yyyy-MM-dd')

But instead of giving me 2000-06-23 it gives me 2000-06-22. Is this a bug on Luxon or I need to do something to get the correct date?

Uh, why not just date.toJSDate()?

According to its docs, fromJSDate defaults to creating a DateTime instance in the local (system) timezone. If you expect another UTC date back, you need to specify that:

DateTime.fromJSDate(jsDate, {zone: 'utc'}).toFormat('yyyy-MM-dd')
