synchronous
SING-kruh-nuhs/ˈsɪŋkrənəs/
Occurring or operating at the same time or with coordinated timing.

Etymology
“Together” and “time” describe events sharing the same moment. The meaning also extends to repeated events that keep matching one another in timing, rather than merely coinciding once.
In context
