How long it lasts

The Moon mahadasha lasts 10 years. Antardasha = 10×17/120 = 170/120 = 1.416667 years, i.e. about 1 year, 5 months.

Here 1 year = 365.25 days.

The order of the antardashas

The Moon mahadasha opens with Moon's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Moon → Mars → Rahu → Jupiter → Saturn → Mercury → Ketu → Venus → Sun. The Mercury antardasha is the sixth in this sequence and begins 5 years, 10 months after the mahadasha starts.

What tradition holds

Tradition links the Moon mahadasha with the mind, feelings and home, and reads the Mercury antardasha as adding a note of learning, communication and practical skill. Mind meets intellect, a blend linked with reading, writing and conversation. The real picture comes from the signs and houses of both planets in the chart.
