API

generate(options?: Options): string

Options (all optional):

  • year - number in range 1800-2299
  • month - number in range 1-12 where 1 is January and 12 is December
  • day - number in range 1-31
  • sex - string (case insensitive) K or F for female and M for male
  • prettyUnique - boolean true|false - useful when used in some sort of automation tests - generates
pesel based on current date, using month, day, hour, minutes and seconds from new Date().
Important note. Because script accepts input, that could create invalid date, the non-strict solution of date computation was choosen. Example: generate({month: 2, day: 31}) - of course February (2. month) does not have 31 days, so that the input is incorrect. But script uses new Date() constructor to compute final birth date, and it will first generate random year (let's say 2017) and then use new Date() with that year and provided month and day. The resulting date will be 2017-03-03 (3rd of March).
