日期问题 我需要得到一个到年底的时间,如现在六月份,要得到年底,假设某年12月份有31日时,则得到XX年12月31 23:59,但是有一个问题就是我怎么知道这个有没有31,年底是到30止还是到31日止,怎么去算,请各位回答。 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 你也可以用DateUtils单元的EndOfTheYear或者EndOfAYear函数来获取年底的时间。 有人写了函数转换日期为农历,那个单元好像是datecn你看能不能搜得到,如:小寒,大寒等这些节日就没有,不过应该可以在上面的基础上自己再代码实现 //delphi代码,我抄的///DELPHI的代码,可以在C++ Builder中编译。unit DateCn;interfaceuses Windows, SysUtils, Controls;const //农历月份数据,每年4字节,从1901年开始,共150年 //数据来源:UCDOS 6.0 UCT.COM //分析整理:Copyright (c) 1996-1998, Randolph //数据解析: //如果第一字节的bit7为1,则该年1月1日位于农历12月,否则位于11月 //第一字节去除bit7为该年1月1日的农历日期 // 第二字节 第三字节 //bit: 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 //农历月份:16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 //农历月份指的是从该年1月1日的农历月份算起的顺序号 //农历月份对应的bit为1则该月为30日,否则为29日 //第四字节为闰月月份 CnData: array[0..599] of Byte = ( $0b,$52,$ba,$00,$16,$a9,$5d,$00,$83,$a9,$37,$05,$0e,$74,$9b,$00, $1a,$b6,$55,$00,$87,$b5,$55,$04,$11,$55,$aa,$00,$1c,$a6,$b5,$00, $8a,$a5,$75,$02,$14,$52,$ba,$00,$81,$52,$6e,$06,$0d,$e9,$37,$00, $18,$74,$97,$00,$86,$ea,$96,$05,$10,$6d,$55,$00,$1a,$35,$aa,$00, $88,$4b,$6a,$02,$13,$a5,$6d,$00,$1e,$d2,$6e,$07,$0b,$d2,$5e,$00, $17,$e9,$2e,$00,$84,$d9,$2d,$05,$0f,$da,$95,$00,$19,$5b,$52,$00, $87,$56,$d4,$04,$11,$4a,$da,$00,$1c,$a5,$5d,$00,$89,$a4,$bd,$02, $15,$d2,$5d,$00,$82,$b2,$5b,$06,$0d,$b5,$2b,$00,$18,$ba,$95,$00, $86,$b6,$a5,$05,$10,$56,$b4,$00,$1a,$4a,$da,$00,$87,$49,$ba,$03, $13,$a4,$bb,$00,$1e,$b2,$5b,$07,$0b,$72,$57,$00,$16,$75,$2b,$00, $84,$6d,$2a,$06,$0f,$ad,$55,$00,$19,$55,$aa,$00,$86,$55,$6c,$04, $12,$c9,$76,$00,$1c,$64,$b7,$00,$8a,$e4,$ae,$02,$15,$ea,$56,$00, $83,$da,$55,$07,$0d,$5b,$2a,$00,$18,$ad,$55,$00,$85,$aa,$d5,$05, $10,$53,$6a,$00,$1b,$a9,$6d,$00,$88,$a9,$5d,$03,$13,$d4,$ae,$00, $81,$d4,$ab,$08,$0c,$ba,$55,$00,$16,$5a,$aa,$00,$83,$56,$aa,$06, $0f,$aa,$d5,$00,$19,$52,$da,$00,$86,$52,$ba,$04,$11,$a9,$5d,$00, $1d,$d4,$9b,$00,$8a,$74,$9b,$03,$15,$b6,$55,$00,$82,$ad,$55,$07, $0d,$55,$aa,$00,$18,$a5,$b5,$00,$85,$a5,$75,$05,$0f,$52,$b6,$00, $1b,$69,$37,$00,$89,$e9,$37,$04,$13,$74,$97,$00,$81,$ea,$96,$08, $0c,$6d,$52,$00,$16,$2d,$aa,$00,$83,$4b,$6a,$06,$0e,$a5,$6d,$00, $1a,$d2,$6e,$00,$87,$d2,$5e,$04,$12,$e9,$2e,$00,$1d,$ec,$96,$0a, $0b,$da,$95,$00,$15,$5b,$52,$00,$82,$56,$d2,$06,$0c,$2a,$da,$00, $18,$a4,$dd,$00,$85,$a4,$bd,$05,$10,$d2,$5d,$00,$1b,$d9,$2d,$00, $89,$b5,$2b,$03,$14,$ba,$95,$00,$81,$b5,$95,$08,$0b,$56,$b2,$00, $16,$2a,$da,$00,$83,$49,$b6,$05,$0e,$64,$bb,$00,$19,$b2,$5b,$00, $87,$6a,$57,$04,$12,$75,$2b,$00,$1d,$b6,$95,$00,$8a,$ad,$55,$02, $15,$55,$aa,$00,$82,$55,$6c,$07,$0d,$c9,$76,$00,$17,$64,$b7,$00, $86,$e4,$ae,$05,$11,$ea,$56,$00,$1b,$6d,$2a,$00,$88,$5a,$aa,$04, $14,$ad,$55,$00,$81,$aa,$d5,$09,$0b,$52,$ea,$00,$16,$a9,$6d,$00, $84,$a9,$5d,$06,$0f,$d4,$ae,$00,$1a,$ea,$4d,$00,$87,$ba,$55,$04, $12,$5a,$aa,$00,$1d,$ab,$55,$00,$8a,$a6,$d5,$02,$14,$52,$da,$00, $82,$52,$ba,$06,$0d,$a9,$3b,$00,$18,$b4,$9b,$00,$85,$74,$9b,$05, $11,$b5,$4d,$00,$1c,$d6,$a9,$00,$88,$35,$aa,$03,$13,$a5,$b5,$00, $81,$a5,$75,$0b,$0b,$52,$b6,$00,$16,$69,$37,$00,$84,$e9,$2f,$06, $10,$f4,$97,$00,$1a,$75,$4b,$00,$87,$6d,$52,$05,$11,$2d,$69,$00, $1d,$95,$b5,$00,$8a,$a5,$6d,$02,$15,$d2,$6e,$00,$82,$d2,$5e,$07, $0e,$e9,$2e,$00,$19,$ea,$96,$00,$86,$da,$95,$05,$10,$5b,$4a,$00, $1c,$ab,$69,$00,$88,$2a,$d8,$03);
