 The transition from the asymptotic giant branch (AGB) to the final white dwarf (WD)stage is arguably the least understood phase in the evolution of single low- and intermediate-mass stars (0.8 ∼ < MZAMS/M ∼ < 8...10). Here we briefly review the progress in the last 50 yearsof the modeling of stars during the post-AGB phase. We show that although the main features,like the extreme mass dependency of post-AGB timescales were already present in the earliestpost-AGB models, the quantitative values of the computed post-AGB timescales changed everytime new physics was included in the modeling of post-AGB stars and their progenitors. Then wediscuss the predictions and uncertainties of the latest available models regarding the evolutionarytimescales of post-AGB stars
