A date math parser compatible with elastic search format
npm install datemath-parser
> The date type supports using date math expression when using it in a query/filter (mainly makes sense in range query/filter).
> The expression starts with an "anchor" date, which can be either now or a date string (in the applicable format) ending with ||.
> It can then follow by a math expression, supporting +, - and / (rounding).
> The units supported are y (year), M (month), w (week), d (day), h (hour), m (minute), and s (second).
> Here are some samples: now+1h, now+1h+1m, now+1h/d, 2012-01-01||+1M/d.
> Note, when doing range type searches, and the upper value is inclusive, the rounding will properly be rounded to the ceiling instead of flooring it.
javascript
var parser = require('datemath-parser');
parser.parse(dateMathExpression, [now], [roundUp], [timeZone]);
