Sketch a full-year calendar in one afternoon

Sketch a full-year calendar in one afternoon
The top-down order that keeps it light:
— Block the 4 big campaigns or launches first, one per quarter [framework]
— Drop in fixed annual dates: anniversaries, recurring sales, niche events [free]
— Assign each month a single theme, don't plan posts yet [template]
— Mark the two slow months as 'evergreen + rest'
— Stop there; planning past month-level a year out is wasted detail
