We use low‐degree acoustic modes obtained by the BiSON to estimate the main‐sequence age t⊙ of the Sun. The calibration is accomplished by linearizing the deviations from a standard solar model the seismic frequencies of which are close to those of the Sun. Formally, we obtain the preliminary value t⊙ = 4.68±0.02 Gy, coupled with an initial heavy‐element abundance Z = 0.0169±0.0005. The quoted standard errors, which are not independent, are upper bounds implied under the assumption that the standard errors in the observed frequencies are independent.
