"Monday or Tuesday" by Virginia Woolf is a short story collection published in 1921. The book contains eight experimental stories that capture the fleeting impressions and sensations of ordinary life. Printed by The Hogarth Press with woodcuts by Vanessa Bell, the collection includes previously published pieces like "The Mark on the Wall" and "Kew Gardens" alongside new works. The title reflects Woolf's belief that fiction should illuminate the continuous stream of impressions that shape everyday experience, whether Monday or Tuesday.
