CHRONOS

Cyberpunk Monthly Calendar Constructor — a free, in-browser tool that builds a cyberpunk-styled monthly calendar and exports it as a clean PNG. Great for TTRPG game masters and netrunner handouts.

Features

• Pick any month / year and render a styled monthly grid.
• Year mode — switch the VIEW toggle to YEAR for a full-year poster of 12 mini-months, in a 4×3 or 3×4 lattice (always rendered at L size, 2× export).
• PNG export — one click saves the calendar as a transparent-corner PNG.
• Color controls — set the Main (grid/frame) and Accent (text/glow) colors from 19 preset swatches per palette, or pick any custom color.
• Day highlights — click a day to cycle a highlight through 5 colors, ctrl+click to stamp the last color, right-click to clear, ctrl+right-click to clear all; marks persist per date and export with the PNG.
• Size presets — S / M / L cap the calendar width; the exported PNG width matches the on-screen // PREVIEW: NxMpx label (L renders at 2× for crisper output).
• First weekday toggle — start the week on Monday or Sunday.
• Weekend highlighting — independently highlight Saturday and/or Sunday.
• Custom background — upload, paste, or drag-and-drop an image onto the calendar; crop it to the calendar's aspect (with recrop), tune brightness, and it exports with the PNG.
• Themes — collapsible left THEMES drawer with live hover-preview; ships DEFAULT and a Y2K BUBBLEGUM theme (glossy candy bubble cells, scoop-free round frame, gradient day numbers). Each theme keeps its own Main/Accent color memory.
• 8 languages — separate UI language (top-right) and calendar language (config panel): EN, RU, FR, DE, ES, IT, JA, ZH. Calendar month/weekday names come from the browser's Intl API.
• Self-contained fonts — JetBrains Mono is embedded as base64 @font-face rules (latin, latin-ext, cyrillic), so the typeface renders correctly in the exported PNG without any external font fetch. JA/ZH calendars fall back to a system font.

Usage

Open index.html in any modern browser — there is no build step. Pick a month, tweak the colors and layout, then click ⬇ SAVE PNG.

Built with

• augmented-ui — clipped/beveled cyberpunk panel styling
