 This R-package offers a suite of functions designed to assist dendrochronologists in inferring estimates for felling dates, derived from dated tree-ring series. The presence of partially preserved sapwood (*sw*) allows to estimate the missing number of sapwood rings, and to report an interval in which the actual felling date (*fd*) likely falls.
