Kiro, the Marathi rendering of Cheiro (William John Warner, 1866–1936), was a celebrated Irish astrologer, numerologist, and palmist whose works achieved widespread international popularity. Known for his precise predictions and detailed analyses of hands, dates, and astrological charts, Cheiro's methods became highly influential in esoteric circles globally, including in India. Kiro's Marathi books, published by Gajanan Book Depot, Maharashtra, include तुमची जन्मतारीख काय सांगतेय ? (What is Your Date of Birth?), तुमचा भाग्योदय कसा होईल ? (How Will Your Luck?), किरो यांवे हातावरून भविष्यवेध (Prophecy By The Hands of Kiro), and किरो यांचे जन्मदिनांकाचे अंकसिद्धांत (The Theory Of Glass Numbers on Kiro's Birthday), all of which explore various facets of numerology, palmistry, and destiny prediction based on his renowned systems.
