This paper proposes modeling the semantics of natural-language calendar expressions as extended regular expressions (XREs).The approach covers expressions ranging from plain dates to such ones as the second Tuesday following Easter.The pa- per presents basic calendar XRE constructs, sample calendar expressions with their representations as XREs, and possible applications in reasoning and natural-language generation.
