Dim JD, WD, Days, SunDown, TimeArea, X, ACOS, Arr, Today
JD = 113.8 '经度，东为正西为负，我国都是东经
WD = 27.55 '纬度，北为正南为负，我国都是北纬
TimeArea = 8 '时区，东正西负，我国有东九、东八、东七、东六、东五五个时区
TodAy = Year(Now) & "年" & Month(Now) & "月" & Day(Now) & "日" 
Days = DateDiff("d", Year(Now) & "-1-1 00:00:00", Now) + 1 
X = -TAN(-23.4*COS(2*3.14*(Days+9)/365)*3.14/180)*TAN(WD*3.14/180)
ACOS = Atn(-X / Sqr(-X * X + 1)) + 2 * Atn(1)
SunDown = Round(24*(1+(TimeArea*15-JD)/180)-24*(180+TimeArea*15-JD-ACOS*180/3.14)/360, 2)
Arr = Split(SunDown, ".")
SunDown = Arr(0) & ":" & Int((0&"."&Int(Arr(1)))*60) 
WScript.Echo "本地" & Today & "的日落时间为：" & SunDown

这个VBS只能显示日落时间，哪位大神把日出时间也加进去？谢谢
