Google表格：如果周数在日期范围内

Question

我需要一个IF语句来搞清楚：

=If(WEEKNUMBER is between STARTDATE and ENDDATE;1;0)

为了测试，我们可以说：

A1 = Startdate

B1 = Enddate

C1 =周数

D1 = IF-statement

Answer 1

D1使用WEEKNUM（）函数：

=if(and(weeknum(A1) <= C1; C1 <= weeknum(B1))=true; 1; 0)

例如：

__|     A    |     B     |     C     |      D     |
1 | 1/1/2016 | 1/16/2016 |     2     |      1     |
2 | 1/1/2016 | 1/16/2016 |     4     |      0     |
