What is DATES3M9. date format? How do I convert it to DATE9. format?

[Sujithpeta]

Hey, I've a column "DeathDate" in my dataset which is supposed to be a date variable, but the data format and type are numerical, the format is also shown as DATES3M9.

I didn't get any search result on this date format on google. Wondering if it's possible to convert this to DATE9. Or column is made such that to de-identify. Below is how the data points look in the data.

Thanks

If they are just numbers, you could apply any format you want

data dd;
input dd;
format dd date9.;
cards;
