datetime_iso8601

Parse ISO8601 date-times! But you should probably use RFC3339 instead

The ISO8601 date-time format is complex. Unless you have particular need for things like 2024-W11 you are better off using the RFC3339 format, which the gleam_time package supports.

gleam add datetime_iso8601@1

import datetime_iso8601

pub fn main() -> Nil {
  assert datetime_iso8601.parse("2024-W11")
    == Ok(datetime_iso8601.YearWeek(2024, 11))
}
