I am trying to calculate the age based on birth date using eeptools in R.

I follow some tutorial pages but it didn't work

My raw dataset is like below :

```   Born       bioguide
1946-05-27    A000370
1979-06-19    A000371
1980-04-18    A000367
1958-06-12    A000369
1948-03-23    B001291
1973-07-24    B000213
1949-09-15    B001281
1950-03-12    B001271
1952-04-20    B001292
1950-06-20    B001293
```

And also my desired output is (Age may be little wrong since I calculate manually):

```   Born        Age
1946-05-27     72
1979-06-19     41
1980-04-18     40
1958-06-12     62
1948-03-23     72
1973-07-24     47
1949-09-15     71
1950-03-12     70
1952-04-20     68
1950-06-20     70
```

Many thanks,

It looks like eeptools has an `age_calc()` function.

```your_data <- data.frame(stringsAsFactors=FALSE,
Born = c("1946-05-27", "1979-06-19", "1980-04-18", "1958-06-12",
"1948-03-23", "1973-07-24", "1949-09-15", "1950-03-12",
"1952-04-20", "1950-06-20"),
bioguide = c("A000370", "A000371", "A000367", "A000369", "B001291",
"B000213", "B001281", "B001271", "B001292", "B001293")
)

library(eeptools)

your_data\$age <- eeptools::age_calc(dob = as.Date(your_data\$Born),
enddate = Sys.Date(),
units = 'years')

your_data
#>          Born bioguide      age
#> 1  1946-05-27  A000370 73.62459
#> 2  1979-06-19  A000371 40.56158

#> 4  1958-06-12  A000369 61.58075
#> 5  1948-03-23  B001291 71.80328
#> 6  1973-07-24  B000213 46.46569
#> 7  1949-09-15  B001281 70.32048
#> 8  1950-03-12  B001271 69.83281

Not sure how to do it with eptools, but it should be simple enough without it.

```dta <- data.frame(born = as.Date(c("1934-02-02", "1956-02-05"),
id=c("A","B")))
dta\$age <-  as.numeric(round((as.Date("2020-01-01")-dta\$born)/365))
```

age_calc function, his function calculates age in days, months, or years from a date of birth to Function to calculate age from date of birth. age_calc(dob, enddate = Sys.Date ()� I am facing the common task of calculating the age (in years, months, or weeks) given the date of birth and an arbitrary date. The thing is that quite often I have to do this over many many records (>300 millions), so performance is a key issue here.

You can use package `lubridate` to calculate the age via `time_length()` + `difftime()`

```library(lubridate)
df <- within(df,age <- round(time_length(difftime(Sys.Date(),as.Date(Born)),"years")))
```

such that

```> df
Born bioguide age
1  1946-05-27  A000370  74
2  1979-06-19  A000371  41

change a column from birth date to age in r, From the comments of this blog entry, I found the age_calc function in the eeptools package. things wrapped up nicely in a function, as in my answer using the eeptools package. @param dob date-of-birth, the day to start calculating age. This free age calculator computes age in terms of years, months, weeks, days, hours, minutes, and seconds, given a date of birth. Determine the time between today and your next birthday using the date calculator, or explore hundreds of other calculators addressing math, health, fitness, finance, and more.

Efficient and accurate age calculation (in years, months, or weeks) in , To get the change in clock time (in years, months, days, etc) you need to use units = "years"), eeptools = age_calc(dob = birthdate, enddate = givendate, units � Then drag the fill handle down to the cells that you want to get the age, all ages from the birth date to today have been calculated, see screenshot: Tip: If you need to get the age from birth date to death date instead of current date, please apply the below code: Calculate age from the birth of date before 1900 to death date:

calculating age, I used lubridate package to specify that DOB and Test_date were dates with Day It does a really nice job of calculating age even when I use my date variables. You can also create an excel formula based on the INT function or ROUNDDOWN function, the YEARFRAC function and the TODAY function to calculate age from birth of date. The YEARFRAC function can be used to calculate the fraction of the year represented by the number of whole days between the date of birth and the current date.
