How long it lasts

The Jupiter mahadasha lasts 16 years. Antardasha = 16×17/120 = 272/120 = 2.266667 years, i.e. about 2 years, 3 months, 6 days.

Here 1 year = 365.25 days.

The order of the antardashas

The Jupiter mahadasha opens with Jupiter's own antardasha (BPHS ch. 51: the first antardasha belongs to the dasha lord), then the planets follow in Vimshottari order: Jupiter → Saturn → Mercury → Ketu → Venus → Sun → Moon → Mars → Rahu. The Mercury antardasha is the third in this sequence and begins 4 years, 8 months after the mahadasha starts.

What tradition holds

Tradition links the Jupiter mahadasha with knowledge, guidance and dharma, and reads the Mercury antardasha as adding a note of learning, communication and practical skill. Intellect meets wisdom, linked with study, writing and counsel. The real picture comes from the signs and houses of both planets in the chart.
