How long it lasts

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

Here 1 year = 365.25 days.

The order of the antardashas

The Mercury mahadasha opens with Mercury's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Mercury → Ketu → Venus → Sun → Moon → Mars → Rahu → Jupiter → Saturn. The Moon antardasha is the fifth in this sequence and begins 7 years, 1 month after the mahadasha starts.

What tradition holds

Tradition links the Mercury mahadasha with learning, communication and practical skill, and reads the Moon antardasha as adding a note of the mind, feelings and home. 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.
