在Excel中计算年龄
[英]Calculate age in excel
问题描述
I have a date of birth in excel 23-05-2015(dd/mm/yyyy) and I need to calculate age.I tried the formula =DATEDIF(C3,TODAY(),"Y") but am getting an error as #VALUE!.When I evaluate the formula it shows as =DATEDIF("23/05/2015",42866,"Y"). 
我的出生日期是excel 23-05-2015（dd / mm / yyyy），我需要计算年龄。我尝试了公式= DATEDIF（C3，TODAY（），“ Y”），但由于出现错误#VALUE!。当我评估公式时，它显示为= DATEDIF（“ 23/05/2015”，42866，“ Y”）。 I guess it is because of date format (dd/mm/yyyy), is there any method where I can achieve this. 我猜是因为日期格式（dd / mm / yyyy），有什么方法可以实现这一点。

Simply write =Today-C3 and then press Ctrl+1 and select Number for the format. 只需编写=Today-C3 ，然后按Ctrl+1并选择Number作为格式。 The answer is in days. 答案是几天之内。
Or try like this: 或者尝试这样：
=DATEDIF(DATE(YEAR(A24),MONTH(A24),DAY(A24)),TODAY(),"Y")

You need to convert string to date inside DATEDIF() : 您需要在DATEDIF()字符串转换为日期：
=DATEDIF(DATE(RIGHT(A1,4),MID(A1,4,2),LEFT(A1,2)),TODAY(),"y")
And if you love big formulas: 如果您喜欢大公式：
=DATE(RIGHT(A1,LEN(A1)-FIND("@",SUBSTITUTE(A1,"-","@",(LEN(A1)-LEN(SUBSTITUTE(A1,"-","")))))),MID(A1,FIND("-",A1)+1,FIND("@",SUBSTITUTE(A1,"-","@",(LEN(A1)-LEN(SUBSTITUTE(A1,"-","")))))-FIND("-",A1)-1),LEFT(A1,2))

I used the following formula which returned me the correct answer in years. 我使用以下公式，多年来返回了正确答案。
=DATEDIF(DATE1, DATE2, "Y") = DATEDIF（DATE1，DATE2，“ Y”）
