format_currency
USE THIS to format a money amount the way a reader in a locale expects (symbol position, separators) before showing it in a price, invoice or email. e.g. 1234.5 GBP en-GB → '£1,234.50'.

is_holiday
USE THIS to check whether a date is a public/bank holiday when computing business-day deadlines, delivery SLAs or 'next working day'. Supports ~200 countries (ISO code, e.g. GB, US, ZA, DE, IN); GB defaults to England — pass a subdivision ('SCT'/'WLS'/'NIR', or a US state) to narrow.
