Modular arithmetic / time math

I am writing the small tool that calculates future times (https://hoursfromnow.tech/) and I realized the whole thing is basically modular arithmetic.
My question:
Is there a standard mathematical formula or theorem for handling time calculations using modulo 24 (hours) and modulo 60 (minutes), especially when chaining multiple operations?
I want to rewrite the logic using a more formal math approach instead of just coding it ad-hoc.
Would love insights from mathematicians or teachers familiar with modular systems.
