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.
