Time Until
A single purpose javascript module that compares two dates and reports the distance in user friendly years, months, weeks, days, hours, and seconds.
Interface
timeUntil(date, context)
- date: the input date, as a valid javascript
Date
object - context: a comparison date, defaults to the current time using
new Date()
Basic usage:
const { unit, value, string, past } = timeUntil(date)
console.log('Unit', unit) // /(now)|((second|minute|hour|day|week|month|year)s?)/
console.log('Value', value) // /(d+)/
console.log('String', string) // 10 weeks ago, 5 days time, 2 hours, 1 minute ago, now
console.log('Past', past) // true|false
Calling timeUntil(date)
returns an object; the .string
property can be displayed straight the user, but if you want the break down, then the .unit
, .value
, and .past
/ future status is available as well.
