Don't worry about the world coming to an end today. It is already tomorrow in Australia.

The line uses a wry, time-zone-based joke to puncture apocalyptic anxiety: if the “end of the world” were scheduled for “today,” parts of the globe are already in “tomorrow,” so the fear is revealed as parochial and illogical. More broadly, it encourages perspective-taking—recognizing how our sense of urgency is often a product of where we stand, temporally and psychologically. The humor is characteristic of Schulz’s gentle skepticism about worry and catastrophizing: by reframing the premise with a simple fact about global time, the quote invites the reader to step outside panic and regain proportion.
