We calculate the third homology of $\mathrm{SL}_2(\mathbb{Q})$ withhalf-integral coefficients. Corresponding to each prime $p$ there is anoperator on this group with square the identity. The kernel of the (splitsurjective) homomorphism to the indecomposable $K_3$ of $\mathbb{Q}$ is a thedirect sum over all primes of the $(-1)$-eigenspaces of these operators. The$(-1)$-eigenspace of the operator corresponding to the prime $p$ is cyclic oforder the odd part of $p+1$.
