Verdict
The clearest difference is ads: Date Calculator ± at none against Age Calculator's shown. Date Calculator ± also leads on update cadence (daily vs every 3 weeks). Age Calculator's advantage is iOS requirement (13.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
