How to set Luxon DateTime to start of day (reset time)

Question

I have trawled the docs, but cannot find a a helper to reset the time of a Luxon DateTime.

I can start with a standard date:

export const getDateOnly = (date: Date = new Date()) =>  new Date(
  date.getFullYear(),
  date.getMonth(),
  date.getDate()
)

export const today = () => DateTime.fromJSDate(getDateOnly());

but this seems like a common scenario and I might have just missed it?

With example:

export const today = () => DateTime.now().startOf('day');

it works with the plus function as well, so if you want to get tomorrow as a date, starting at 00:00:00 it will be like so: const tomorrow = DateTime.now().plus({ days: 1 }).startOf('day'); – Chambliss

I would even say DateTime.now().toUTC().startOf('day') for the UTC start of today – Murk
