Let's start with a simple example...
Date instance representing 72 hours before the present.
Neat. What about the future?
Easy! Note the use of
minute rather than
minutes. The two are synonymous;
singular and plural properties exist for each of the supported units.
Decimals? You betcha:
In fact, they read very nicely since they don't require an awkward double dot.
What about dates relative to other points in time?
var tomorrow = 1..day.from_now var halloween = new Date("31 October 2011") var christmas = new Date("25 December 2011") 1..week.from(tomorrow) 2..days.after(halloween) 1..week.before(christmas)
after are synonymous; use whichever reads better.
This is pleasing, you may be thinking, but I'd never say “one week from tomorrow” – it sounds a bit stiff.
Well, if you must...
var a = NaturalDate.a var an = NaturalDate.an a.week.from(tomorrow) a.fortnight.from_now an.hour.ago
Oh, and I should mention, you can add
NaturalDate instances using the
Can you help me with date comparison? To determine whether an event occurred more than a week ago I have to ask whether its numeric representation is less than that of "a week ago". It makes my head hurt.
Perhaps you find this more natural?
A practical example:
var user_registered = db.get(id).registration_date if (user_registered.less_than(15..minutes).ago) $("#tips").show()
after can follow
if (costume_returned.more_than(2..days).after(halloween)) apply_late_fee()
There's also an
either_side_of method which does what it says on the tin:
var unfortunate = birthday.less_than(3..days).either_side_of(christmas)
That just about covers it.
Running the test suite
npm install npm test
One last thing...
To be clear, an.hour.ago fiddles with
Two properties are added to
The following properties are added to
Each of these properties has a "getter" which returns a

NaturalDate is the only property added to the global object.
