Converting year and month ("yyyy-mm" format) to a date?
(9 answers)
Closed 8 months ago.
I currently have a database with dates in character format yyyy-mm format. e.g. 2009-01 and missing values.
I'm struggling to convert this into a date format.
You could use ym from lubridate package:
lubridate::ym('2009-01')
#[1] "2009-01-01"

What are the "standard unambiguous date" formats for string-to-date conversion in R?

For my dataset, the Date variable has dates in the format of this example: 19-Feb-03
I want to change the above character format dates in the column to a Date format. (As I have to do time series analysis later on)
I tried using the as.Date() method but it didn't work.
x <- '19-Feb-03'
lubridate::ymd(x)
"2019-02-03"
Not sure whether 19 is year or day. You can try lubridate package
x<-"19-Feb-03"
library(lubridate)
ymd(x)
dmy(x)

as.Date(MYDATE, format = "%m/%d/%y", origin = "1900-01-01")
AND
format(MYDATE, "%m/%d/%Y")
But returned just
NA
Using lubridate we can:
ymd(MY_DATE)

I've got a character like this:
"2008-11" and I want to convert it in a date format. (only year and month)
I've already tried with zoo package:
yearmon("2008-11")
but it returns a NUM. I want a Date as structure. It should return 2008-11.
Which is the fastest way?
Thanks
library(anytime)
a <- anydate("2008-11")
> class(a)
[1] "Date"
> a
[1] "2008-11-01"

I have date in character vector. I need to convert it to date format.
For example :
Month = "202005"
Output should be May-20. It should be in date format so that I can use to filter some dates. Similarly 201912 should return Dec-19
zoo has a function called yearmon().
library(zoo)
month <- "202005"
as.yearmon(month, "%Y%m")
# "May 2020"

I want to convert mmm-yy(Jan-85) date format into yyyy-mm-dd (1985-01-02)date format in R.
One option is to paste the day and convert it to Date class with as.Date and the appropriate format
as.Date(paste0("Jan-85", "-02"), "%b-%y-%d")
#[1] "1985-01-02"
