Often you don’t want to query events between two set dates, but dates relative in time. For instance you might want to display upcoming events this month, or events just finished, etc. Event Organiser allows you to give certain date-related query arguments ‘relative dates’. For example, tomorrow, now, +1 week, third Thursday of this month.

Please note that these strings are interpreted using PHP’s datetime object. See allowed statements here. Some PHP versions do not support all the statements.
For example first day of this month is only supported by PHP 5.3+
