" if temporality constitutes the primordial meaning of being of Da-sein, and if this being is concerned about its being in its very being, then care must need “time” and thus reckon with “time”. The temporality of Da-sein develops a “time calculation”. The “time” experienced in such calculation is the nearest phenomenal aspect of temporality. From it originates the everyday, vulgar understanding of time "

― Heidegger, Martin
