The reign of Cyrus

Start — no reference given. The year Cyrus' reign over Persia began (according to extra-biblical sources) is 559 BCE which is 27 years after the destruction of the Temple in 586 (3376 AH + 27) = 3403
End — no reference given. The year Cyrus's reign over Persia ended is the year his reign over Persia began (3403) + the length of his reign (29) = 3432 (530 BCE)

Years are anno hominis — counted from Creation as year 1 — which is the frame the source computes in. The arithmetic behind each boundary is given above rather than assumed.
