Referencing the Date.parse() documentation:

In instances where a time zone is not specified and the string follows an ISO format acknowledged by ES5, UTC is assumed by default.

However, it is essential to be cautious when relying on this behavior, as highlighted in the same source:

It is worth noting that ECMAScript ed 6 draft specifies that date time strings lacking a time zone should be considered local, not UTC.
