daze

Module to manage simple 8-digit integer dates.

npm install daze

Usage

• To Date - Get a standard Javascript Date object.
• To Daze - Get an 8-digit integer to save/JSON/compare with.
• Is Late - Determine if dateA has occurred since dateB.
• Is Greater - Compare two dates to find if dateA comes after dateB.
• Is Lesser - Compare two dates to find if dateA comes before dateB.
• Days Past - Get a whole integer representing the amount of days from dateA since dateB (can be negative - will still be whole.)
• Days Until - Get a whole integer representing the amount of days from dateA to dateB (can be negative - will still be whole.)

String date formats may conflict with your processing time zone. If you receive a formatted date string, from something like Date.toISOString, from a source in another time zone then you'll encounter a conflict when daze'ing. Try sharing daze'ed values or, instead, daze formatted string values from sources with expected time zones. Maybe this can be a to-do?.. maybe regex/parse values out of strings of known standards?

All examples below assume April 3rd, 2016 - the day of this writing - if not otherwise specified.

Using Two Dates

Both dateA and dateB can be different date types - those types are shown in examples further below.

var dateA = 20160401;
var dateB = 20160501;

daze(dateA).toDaze();
daze(dateA).toDate();
daze(dateA).late(dateB);
daze(dateA).past(dateB);
daze(dateA).until(dateB);
daze(dateA).greater(dateB);
daze(dateA).lesser(dateB);

Using No Dates

When you do not provide a date, today - or daze().toDaze() - is assumed.

daze().toDaze(); // 20160403

daze(20160403).toDaze() === daze().toDaze();

Using Different Date Types

All the below would return 20160403.

daze().toDaze();
daze(20160403).toDaze();
daze(new Date).toDaze();
daze(1459730291984).toDaze();

Programmatically

Standard Usage Examples

var daze = require("daze");

/* As of this writing, this month - April - has
// 30 days. The below examples illustrate some
// general usage with real results.
*/
console.log(daze); // "[Function: daze]"

console.log(daze().toDaze()); // 20160403
console.log(daze().toDate()); // Sun Apr 03 2016 19:09:49 GMT-0500 (CDT)

console.log(daze().late(20160402)); // true
console.log(daze().late(20160403)); // true
console.log(daze().late(20160404)); // false

console.log(daze().past(20160401)); // 2
console.log(daze().past(20160403)); // 0
console.log(daze().past(20160430)); // -27

console.log(daze().until(20160401)); // -2
console.log(daze().until(20160403)); // 0
console.log(daze().until(20160430)); // 27

console.log(daze(20160101).greater(20150101)); // true
console.log(daze(20160101).lesser(20170101)); // true

  // like the programmatic examples above.
