Converts and calculates dates in the Persian (Jalali, Solar Hijri, Shamsi) calendar. Use whenever the user mentions a Jalali, Shamsi or Persian date, month names like فروردین or آبان, years like 1404 or ۱۴۰۵, wants to convert to or from Gregorian, add or subtract days, find the weekday, count days between dates, print a month calendar, or fix a table that mixes calendars, even if they only say "what is this date in the Iranian calendar". Verified against known Nowruz dates.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# persian-dates
Convert between Gregorian and Jalali dates reliably, with Persian digits accepted on input and available on output. Standard library only.

├── SKILL.md
├── scripts/
│ └── jalali.py today, to-jalali, to-gregorian, add, diff, month; importable functions
└── references/
└── calendar.md months, weekdays, leap rule, checked reference dates, data advice
```
## When to use
- Converting a date either way between the two calendars
- Adding days, finding the weekday or the distance between dates
- Showing a month calendar
- Cleaning a column that mixes Jalali and Gregorian dates
- Choosing how to store Persian dates in a database
## Workflow
1. **Identify the calendar** of every date. Years around 1300 to 1500 are Jalali, around 1900 to 2100 are Gregorian. If a value is ambiguous, ask.
2. **Convert with the script** instead of mental arithmetic:
`python3 scripts/jalali.py to-jalali 2026-11-02 --names` gives `دوشنبه 11 آبان 1405`
`python3 scripts/jalali.py to-gregorian ۱۴۰۵/۰۸/۱۱` gives `2026-11-02`
3. **Calculate** with `add` and `diff`:
`python3 scripts/jalali.py add 1405-08-11 --days 30`

How to install
mdr add mehranqadirian/skills/persian-dates@sha256:e17ee72042b4360bThe line at the top of this page pins the label git:20261104.819211d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
