How to print
This calendar is designed to print cleanly on US Letter (8.5 × 11 in) and ISO A4 (210 × 297 mm) paper without scaling. Use your browser's Print menu (or the Print button above), select the orientation that matches the layout you chose — Landscape in this case — and disable headers and footers for the cleanest result. The grid is tuned for monochrome and color printers; holiday shading uses a soft amber that prints well in grayscale.
Other layouts of September 2021
