情景:尝试使用给定的时间段找出结束周数(当前年份的周数)和开始周数。假设 PeriodWeeks = 10.这意味着从今天的周数到过去10周,这肯定会在去年的情况下进行。
代码我有:
perdiodWeeks = 10 ' this is a constant in the code
periodMonths= periodQtrs * 3 ' this calculates month from given number of quarters
endDate = DateAdd("m",-1,Date)
endYear = DatePart("yyyy", endDate)
endMonth = DatePart("m", endDate)
startDate = DateAdd("m", -(periodMonths-1), endDate)
startYear = DatePart("yyyy", startDate)
startMonth = DatePart("m", startDate)
如何计算以下内容?
startYW ' start year week number
endYW ' end year week number
其中,值为 endYW = 201506, startYW =来自endYW的perdiodWeeks。 06是2015年的当前周数
答案 0 :(得分:1)
计算初始日期(减去#周* 7)并使用可用函数检索所需信息
Option Explicit
Dim periodWeeks
periodWeeks = 10
Dim dateToday, dateStart
dateToday = Now()
dateStart = DateAdd("d",periodWeeks*-7, dateToday)
Dim weekToday, weekStart
weekToday = DatePart("ww",dateToday)
weekStart = DatePart("ww",dateStart)
