How long it lasts

The Rahu mahadasha lasts 18 years. Antardasha = 18×18/120 = 324/120 = 2.700000 years, i.e. about 2 years, 8 months, 12 days.

Here 1 year = 365.25 days.

The order of the antardashas

In the Rahu mahadasha the first antardasha is Rahu's own, because BPHS (ch. 51) says the first antardasha of every dasha belongs to the dasha lord. So this pair opens the mahadasha; the others follow in Vimshottari order: Rahu → Jupiter → Saturn → Mercury → Ketu → Venus → Sun → Moon → Mars.

What tradition holds

Tradition links the Rahu mahadasha with unfamiliar paths, ambition and change. It is the first antardasha of this mahadasha, so tradition sees Rahu's qualities here in their most direct form. It is a period tradition reads as asking for patience and routine; the real picture comes from Rahu's sign and house in the chart.
