Relative time

Duration centric (Luxon)

A relative time describes how far we are, as of now, from an event that happens in the past or in the future. It is a duration relative to now. We focus on the duration, such as 3 hours ago, or in 2 minutes.

zdt.toRelative() // "4 hours ago"
zdt.toRelative() // "in 2 days"

zdt.toRelative({ style: "short" }) // "4 hr. ago"
zdt.toRelative({ style: "narrow" }) // "4h ago"
zdt.toRelative({ unit: "seconds" }) // "300 seconds ago"
zdt.toRelative({ unit: "years" }) // "1 year ago"
zdt.toRelative({ round: false }) // "4.5 hours ago"
zdt.toRelative({ base: anchor }) // "5 years ago"

Calendar centric (Luxon)

It can also describe where the event takes place in the calendar relative to now. We can focus on calendar date components, with low precision, such as today.

zdt.toRelativeCalendar() // "today"
zdt.toRelativeCalendar() // "yesterday"
zdt.toRelativeCalendar() // "tomorrow"
zdt.toRelativeCalendar() // "2 days ago"
zdt.toRelativeCalendar() // "last month"
