Vimshottari Dasha (Sanskrit: विंशोत्तरी दाशा, transliteration: Viṃśottarī Dāśā) is a significant planetary period system in Hindu astrology, also known as Jyotish. The term "Vimshottari" is derived from the Sanskrit words viṃśati (twenty) and uttari (remaining), referring to the 120-year cycle that this system is based upon. In Hebrew, it can be translated as תקופת וימשוטרי (Tkufat Vimshottari). This system is widely used to predict the timing of major life events by assigning specific periods of influence to each planet in the natal chart. The Vimshottari Dasha is considered one of the most important and accurate systems for timing events in Vedic astrology. Each planet is allocated a specific number of years within the 120-year cycle, starting with Ketu (20 years), followed by Venus (20 years), Sun (6 years), Moon (10 years), Mars (7 years), Rahu (18 years), Jupiter (16 years), Saturn (19 years), and Mercury (17 years). The sequence of these planetary periods begins from the position of the Moon in the natal chart at the time of birth.
