Why another date picker? The problem is that most of existing solutions do not follow standards regarding to value property format, that should have “a valid full-date as defined in [RFC 3339]”. In other words representation of date can vary, but the string value should have yyyy-MM-dd format. It helps to work with such values consistently regarding on the current language.

When no spicified polyfill uses browser settings to format displayed date. You can override date presentation globally with `` via content attribute or directly on a HTML element with data-format attribute. Value should be options for the Date#toLocaleString call as a stringified JSON object:
