PCalen is a web-based tool for creating printable calendars, planners, and trackers. It provides yearly, quarterly, monthly, and weekly calendar layouts, as well as undated planners with daily timelines and biweekly views. Users can also create habit, budget, fitness, and baby trackers. The service is free to use and does not require an account; its generated files have no watermark. Users can choose settings such as paper size, orientation, margins, binding edge, week start, holiday region, theme, and fonts. Layout-specific options include yearly columns, week numbers, and weekly schedule hours. Users can add multiple color-coded notes to dates; notes are saved locally in the browser and included in printed or exported files. Settings appear in an on-screen preview and can be adjusted before export. The typical workflow is to select a calendar or template, customize its settings, add notes if needed, and print or download the result. PCalen supports paper sizes from A4 and US Letter to A5 and poster formats, and can export single-page PDFs, yearly PDF batches, or high-resolution PNG images. The interface adapts to desktop, tablet, and phone screens, with a zoomable print preview. Printing uses the browser’s print dialog.
