The day and year obviously are easy, is there a way to easily parse the month from English into number? Thanks!

There's [1] if you're willing to transform the input.

std.datetime specifically does not deal with parsing all formats (generally, this is a HUGE amount of work).

It has 2 parsing formats (3 actually, if you can't the non-EXT and EXT ISO formats): https://dlang.org/phobos/std_datetime_date.html#.DateTime.fromSimpleString, https://dlang.org/phobos/std_datetime_date.html#.DateTime.fromISOExtString

Otherwise, you have to do it yourself.

Note that the 3-letter english name (not capitalized) might match the Month enum: https://dlang.org/phobos/std_datetime_date.html#Month, which means you could possibly parse it with formattedRead.

There are also dub packages, e.g.: https://code.dlang.org/packages/dateparser

The old D1 std.datetime does it using compiler lexing techniques:
