  • Date Conversion Issue

    Hello Statalister,

    I'm trying to convert dates in Stata and I am having an issue with the listed year after conversion. The original data looks like this:

    Code:
    * Example generated by -dataex-. For more info, type help dataex
    clear
    input str14 state_name str2 state_abv byte state_num long date1
    "Alabama"     "AL" 1 44027
    "Alaska"      "AK" 2     .
    "Arizona"     "AZ" 3     .
    "Arkansas"    "AR" 4 44028
    "California"  "CA" 5 44000
    "Colorado"    "CO" 6 44028
    "Connecticut" "CT" 7 43938
    "Delware"     "DE" 8 43946
    "Florida"     "FL" 9     .
    end
    after running the following command: format %td date1, this is what happens.


    state_name state_abv state_num date1
    Alabama AL 1 16jul2080
    Alaska AK 2 .
    Arizona AZ 3 .
    Arkansas AR 4 17jul2080
    California CA 5 19jun2080
    Colorado CO 6 17jul2080
    Connecticut CT 7 18apr2080
    Delware DE 8 26apr2080
    Florida FL 9 .


    Clearly, the dates (month and day) are correct, but not the year portion (these all happened in 2020). This might be a two step process to change the year, but I wanted to see if there was something else that I'm missing. The original dates were recorded a YMD so maybe that's why?

    this looks like a problem that sometimes happens when importing data from Excel; see
    Code:
    help datetime_software##r5
