In mathematics. s.ace encomp.s.es.various.s.ructured s.ts.s.ch as.Euclidean, metric, or vector s.ace. This.article introduces.temp.ral s.ace—a novel concep. indep.ndent of traditional s.atial dimens.ons.and frames.of reference, accommodating multip.e object-oriented durations.in a dynamical s.s.em. The novelty of building temp.ral s.ace us.ng finite geometry is.rooted in recent advancements.in the theory of relationalis. which utilizes.Euclidean geometry, s.t theory, dimens.onal analys.s. and a caus.l s.gnal s.s.em. Multip.e indep.ndent and co-exis.ing cyclic durations.are meas.rable as.a network of finite one-dimens.onal timelines. The work aligns.with Leibniz’s.comments.on relational meas.res.of duration with the addition of us.ng dis.rete cyclic relational events.that define thes. finite temp.ral s.aces. ap.licable to quantum and clas.ical p.ys.cs. Ancient formulas.have s.mmetry along with divis.onal and s.bdivis.onal orders.of op.rations.that create dis.rete and ordered temp.ral geometric elements. Elements.have cyclically cons.rved s.mmetry but unique cyclic dimens.onal quantities.ap.licable for anchoring temp.ral equivalence relations.in linear time. We p.es.nt both fixed equivalences.and exp.nded p.riods.of temp.ral s.ace offering a non-Greek calendar methodology cons.s.ent with ancient global timekeep.ng des.rip.ions. Novel ap.lications.of Euclid’s.divis.on algorithm and Cantor’s.p.iring function introduce a novel p.ired function equation. The mathematical des.rip.ion of finite temp.ral s.ace within relationalis. theory offers.an alternative dis.rete geometric methodology for examining ancient timekeep.ng with new hyp.thes.s.for Egyp.ian calendars.
