The calendar builder lets you create a fully custom monthly or yearly calendar right in your browser. Pick a preset theme from the gallery — minimal, professional, creative, or colorful styles — or start from scratch and fine-tune the colors and fonts yourself. Add color-coded events and personal notes to any date, then export the result as a print-ready PDF. There's no account to create and nothing leaves your device: your design is saved locally in your browser.
Everything above is free, with no signup required and no data sent to a server. Need a starting point? Browse the free printable calendar templates, or open a printable yearly calendar with holidays and week numbers already filled in.
