+A Rust crate for parsing human-readable relative time strings and human-readable datetime strings and converting them to a `DateTime`.

 ## Features

- Parses a variety of human-readable time formats.
+- Parses a variety of human-readable and standard time formats.
 - Supports positive and negative durations.
 - Allows for chaining time units (e.g., "1 hour 2 minutes" or "2 days and 2 hours").

 `num` can be a positive or negative integer.
 `unit` can be one of the following: "fortnight", "week", "day", "hour", "minute", "min", "second", "sec" and their plural forms.

 ## Return Values

-The `from_str` and `from_str_at_date` functions return:

+//! >
+//! > Days of the week may be spelled out in full: ‘Sunday’, ‘Monday’,
+//! > ‘Tuesday’, ‘Wednesday’, ‘Thursday’, ‘Friday’ or ‘Saturday’. Days may be
+//! > abbreviated to their first three letters, optionally followed by a

+//! > A number may precede a day of the week item to move forward supplementary
