const fromDate = DateTime.make(new Date("2024-01-01T12:00:00Z"))
console.log(fromDate._tag) // "Some"

// from parts
const fromParts = DateTime.make({ year: 2024 })
console.log(fromParts._tag) // "Some"

// from string
const fromString = DateTime.make("2024-01-01")
console.log(fromString._tag) // "Some"

const invalid = DateTime.make("not a date")
