calculator for humanity’s peculiar conventions of time
The d3-time module does not implement its own calendaring system; it merely implements a convenient API for calendar math on top of ECMAScript Date. This module is used by D3’s time scales to generate sensible ticks, by D3’s time format, and can also be used directly to do things like calendar layouts.
Node.js is an event-based server-side JavaScript engine.
