Jalali Calendar is an agent skill from TronIsHere/vibefarsiui. Handle dates and times for Iranian users: the Jalali / Solar Hijri calendar (تقویم شمسی، هجری خورشیدی), Saturday-first weeks, Tehran time (+03:30, no DST), Persian month and weekday names, formatting, storage, ranges, reports and holidays. Use whenever a date, time, calendar, date picker, deadline, booking, report period or age appears in a Persian (Farsi) product, or the user says تاریخ شمسی، تقویم فارسی، jalali، شنبه، نوروز.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The licence is MIT.
10 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 7d56b50. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Jalali Calendar loads about 1.6k tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 880 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Run `npx skills add TronIsHere/vibefarsiui --skill jalali-calendar -a claude-code`. Or copy the skill folder (registry/skills/jalali-calendar in TronIsHere/vibefarsiui) into .claude/skills/jalali-calendar in your project. Claude Code loads it when a task matches its description.
Run `npx skills add TronIsHere/vibefarsiui --skill jalali-calendar -a codex`. Or copy the skill folder (registry/skills/jalali-calendar in TronIsHere/vibefarsiui) into .agents/skills/jalali-calendar in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add TronIsHere/vibefarsiui --skill jalali-calendar -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/jalali-calendar, .gemini/skills/jalali-calendar, .github/skills/jalali-calendar and .opencode/skills/jalali-calendar in your project.
SKILL.md names no scripts, command-line tools or credentials: Jalali Calendar is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md flagged 1 warning(s): contains zero-width characters. Read the flagged lines before installing; the check is not a guarantee either way.
Jalali Calendar is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
