See also std/times

import std/times

proc get_current_date(): string =
now().format("yyyy'_'MM'_'dd")

proc main() =
let date = get_current_date()
echo date # 2026_04_26

main()

Note that MM is the month, while mm is the minute. The format string "yyyy_MM_dd" wouldn't work since the underscore ('_') would also be treated as a format specifier. However, there's no such date/time specifier, so we'd get an error. To avoid the error, it must be put between apostrophes: '…'.

However, some characters don't have to be between apostrophes. In addition to spaces, the following characters can be inserted without quoting them: : - , . ( ) / [ ]. A literal ' can be specified with '' (double apostrophes).

Date object → string

See the example above.

String → date object

import std/times

let
text = "20260503"
dt: DateTime = parse(text, "yyyyMMdd")
reformatted: string = dt.format("yyyy-MM-dd")

echo reformatted # 2026-05-03
