Why another date util library

• Small and not a feature creep
• Favors immutability - less bugs and easy to chain functions
• Favors factory methods for creating new instances instead of multi-purpose constructor
• DateTime can contain only valid dates
• Instead of one big file there are several small modules for different purposes:
• Calculations and transformations
• Formatting
• Parsing
• Localizations
• Ranges
• continuouscalendar uses this library

Documentation

Creating dates

DateTime.fromDateTime(2010, 12, 15, 14, 35).plusDays(10).toISOString() returns 2010-12-25T14:35:00

Formatting dates

DateFormat.format(DateTime.fromDate(2010, 12, 15), 'Y-m-d') returns 2010-12-15

DateFormat.shortDateFormat(DateTime.now(), DateLocale.CN) returns 2016年08月13日
