使用方式：
DateTime dt = new DateTime(); //昨天 DateTime yesterday = dt.minusDays(1); //明天 DateTime tomorrow = dt.plusDays(1); //1个月前 DateTime before1month = dt.minusMonths(1); //3个月后 DateTime after3month = dt.plusMonths(3); //2年前 DateTime before2year = dt.minusYears(2); //5年后 DateTime after5year = dt.plusYears(5);
// 获取年月日点分秒 DateTime dt = new DateTime(); //年 int year = dt.getYear(); //月 int month = dt.getMonthOfYear(); //日 int day = dt.getDayOfMonth(); //星期 int week = dt.getDayOfWeek(); //点 int hour = dt.getHourOfDay(); //分 int min = dt.getMinuteOfHour(); //秒 int sec = dt.getSecondOfMinute(); //毫秒 int msec = dt.getMillisOfSecond();
DateTime dt = new DateTime(); //星期 switch(dt.getDayOfWeek()) { case DateTimeConstants.SUNDAY: System.out.println("星期日"); break; case DateTimeConstants.MONDAY: System.out.println("星期一"); break; case DateTimeConstants.TUESDAY: System.out.println("星期二"); break; case DateTimeConstants.WEDNESDAY: System.out.println("星期三"); break; case DateTimeConstants.THURSDAY: System.out.println("星期四"); break; case DateTimeConstants.FRIDAY: System.out.println("星期五"); break; case DateTimeConstants.SATURDAY: System.out.println("星期六"); break; }
取特殊日期 DateTime dt = new DateTime(); //月末日期 DateTime lastday = dt.dayOfMonth().withMaximumValue(); //90天后那周的周一 DateTimefirstday=dt.plusDays(90).dayOfWeek().withMinimumValue();
//时区 //默认设置为日本时间 DateTimeZone.setDefault(DateTimeZone.forID("Asia/Tokyo")); DateTime dt1 = new DateTime(); //计算区间 DateTime begin = new DateTime("2012-02-01"); DateTime end = new DateTime("2012-05-01"); //计算区间毫秒数 Duration d = new Duration(begin, end); long time = d.getMillis(); //计算区间天数 Period p = new Period(begin, end, PeriodType.days()); int days = p.getDays(); //计算特定日期是否在该区间内 Interval i = new Interval(begin, end); boolean contained = i.contains(new DateTime("2012-03-01")); //日期比较 DateTime d1 = new DateTime("2012-02-01"); DateTime d2 = new DateTime("2012-05-01"); //和系统时间比 boolean b1 = d1.isAfterNow(); boolean b2 = d1.isBeforeNow(); boolean b3 = d1.isEqualNow(); //和其他日期比 boolean f1 = d1.isAfter(d2); boolean f2 = d1.isBefore(d2); boolean f3 = d1.isEqual(d2); //格式化输出 DateTime dateTime = new DateTime(); String s1 = dateTime.toString("yyyy/MM/dd hh:mm:ss.SSSa"); String s2 = dateTime.toString("yyyy-MM-dd HH:mm:ss"); String s3 = dateTime.toString("EEEE dd MMMM, yyyy HH:mm:ssa"); String s4 = dateTime.toString("yyyy/MM/dd HH:mm ZZZZ"); String s5 = dateTime.toString("yyyy/MM/dd HH:mm Z");

时区1. //默认设置为日本时间 2. DateTimeZone.setDefault(DateTimeZone.forID("Asia/Tokyo")); 3. DateTime dt1 = new DateTime(); 4. 5. //伦敦时间 6. DateTime dt2 = new DateTime(DateTimeZone.forID("Europe/London")); 8、计算区间1. DateTime begin = new DateTime("2012-02-01"); 2. DateTime end = new DateTime("2012-05-01"); 3. 4. //计算区间毫秒数 5. Duration d = new Duration(begin, end); 6. long time = d.getMillis(); 7. 8. //计算区间天数 9. Period p = new Period(begin, end, PeriodType.days()); 10. int days = p.getDays(); 11. 12. //计算特定日期是否在该区间内 13. Interval i = new Interval(begin, end); 14. boolean contained = i.contains(new DateTime("2012-03-01")); 9、日期比较1. DateTime d1 = new DateTime("2012-02-01"); 2. DateTime d2 = new DateTime("2012-05-01"); 3. 4. //和系统时间比 5. boolean b1 = d1.isAfterNow(); 6. boolean b2 = d1.isBeforeNow(); 7. boolean b3 = d1.isEqualNow(); 8. 9. //和其他日期比 10. boolean f1 = d1.isAfter(d2); 11. boolean f2 = d1.isBefore(d2); 12. boolean f3 = d1.isEqual(d2); 10、格式化输出1. DateTime dateTime = new DateTime(); 2. 3. String s1 = dateTime.toString("yyyy/MM/dd hh:mm:ss.SSSa"); 4. String s2 = dateTime.toString("yyyy-MM-dd HH:mm:ss"); 5. String s3 = dateTime.toString("EEEE dd MMMM, yyyy HH:mm:ssa"); 6. String s4 = dateTime.toString("yyyy/MM/dd HH:mm ZZZZ"); 7. String s5 = dateTime.toString("yyyy/MM/dd HH:mm Z");
