Common questions

Is Project Parva safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

Project Parva

Website | API documentation | Quickstart | Public benchmark | Licensing

Project Parva is an open-source Nepali date/time API and conformance project.

It covers BS to AD, AD to BS, Nepali date validation, holidays, working days, Nepal fiscal year logic, BS month metadata, Panchanga computation, proof receipts, local verification, SDKs, MCP tools, and public regression fixtures.

The project exists because Nepali date bugs often hide until a boundary is hit: a frontend calendar table disagrees with backend data, a payroll month has the wrong number of days, a datepicker accepts an invalid BS date, or a future BS date changes after someone already used it in a workflow.

Parva treats those cases as conformance problems, not just conversion problems. It records source and method provenance, separates exact evidence from review-needed evidence, and gives developers a way to test what their Nepali calendar API or Nepali date converter is actually doing.

Three public claims define the project:

A documented market review dated 2026-08-05 found no second Nepal-focused API combining BS conversion, location-aware astronomical Panchanga, Nepal business rules, future-BS research, replay artifacts, and public conformance.
The future-BS engine reaches 72/72 exact month predictions in chronological rolling validation over the official 2078-2083 BS window, with each target year trained only on earlier years.
The public benchmark and conformance suites ship with fixtures, runners, named-tool results, and per-case output.

The hosted API is a public evaluation deployment. First requests may be slower when the instance wakes up.

Why This Exists

Most Nepali date bugs are small on paper and expensive in context.

Many systems carry hardcoded Bikram Sambat month tables. A backend CSV, a frontend Nepali datepicker bundle, and a reporting job can each have their own copy. They may all look reasonable until one month differs by a day.

That one day can move:

a payroll period,
a fiscal-year boundary,
a certificate or DOB validation,
an invoice/report date,
an attendance or leave record,
a future BS date that should have stayed review-needed.

Software agents add another failure mode: if the tool does not expose source, confidence, and boundary data, the model will often answer as if the date is settled. Parva is built to make those boundaries visible.

The project turns public Nepali date failures into fixtures and checks where the evidence is exact enough. When the evidence is partial, it stays marked for review instead of becoming a fake assertion.

Free Nepali Date Risk Audit

If you maintain Nepal-facing payroll, ERP, accounting, attendance, school, cooperative, public-service, government-form, or datepicker software, you can send one small workflow or sample output.

No integration required. No dependency required. No sales call required. No authority claim.

Good inputs:

10 sample BS/AD date outputs
one payroll, fiscal-year, invoice, attendance, report, certificate, or DOB workflow
one public repo, issue, Nepali datepicker, or library case
one real edge case your team has seen in production or testing

Checks:

BS/AD conversion boundaries
invalid BS dates
month lengths
frontend/backend calendar source drift
fiscal and payroll month boundaries
holiday and working-day assumptions
future BS dates that should be marked review-needed

You get:

a short technical report
pass, warning, and review-needed findings
suggested regression tests
source and provenance notes
authority-boundary notes

What Parva Does

Area	What it provides
Nepali date API	BS to AD, AD to BS, today, validation, month metadata, supported-range metadata
Civil proof mode	Replay-verifiable membranes for conversion, validation, holidays, working days, fiscal years, and BS months
Panchanga engine	Method-docketed sunrise, tithi, nakshatra, yoga, karana, paksha, vara, ephemeris metadata, and proof receipts
Payroll/date-risk audit	CSV/API-oriented decision-support checks for invalid dates, holidays, non-working days, fiscal boundaries, and review-required cases
Local verification	Shared proof fixtures and a buildable `@project-parva/local-kernel` npm package for offline replay checks
SDKs	Python and JavaScript clients with proof modes and conservative verification helpers
Agent/MCP	Read-only, public-safe agent tool wrappers and MCP adapter surfaces that preserve boundaries and review gates
Benchmark	Public Nepali Time Reliability Benchmark for deterministic date reasoning, source awareness, and review behavior
Governance	Source/method dockets, public claims checker, route maturity, OpenAPI drift checks, and reproducible public verification
Research boundary	Future-BS research kept separate from public authority claims, with compatibility shims only where older imports need them

Public Conformance Work

Parva tracks public Nepali date issues and turns them into fixtures or runnable checks when the evidence is exact enough. The suite separates verified public issues, reported issues, partial evidence, business workflow evidence, and future-date review cases.

Project Parva's benchmark work contributed a standalone calendar source consistency guard to yarsa/nepal-compliance.

That check compared duplicated frontend/backend BS month tables. It did not add a Parva dependency, change upstream runtime behavior, or prove production impact.

Run the public issue conformance suite:

py -3.11 tools\conformance_runner\run.py --suite public-nepali-date-issues

Conformance docs:

Public conformance index

Conformance Milestone 001

These fixtures are public regression and review artifacts. They are not calendar publication, legal guidance, tax guidance, payroll approval, banking guidance, or ritual authority.

Who This Helps

Date library maintainers who want regression cases from real public issues.
ERP, payroll, accounting, school, cooperative, and attendance teams that need safer BS/AD boundaries.
Reviewers of public-service or government-form workflows where invalid BS dates should not slip through.
Developers building a Nepali calendar API, Bikram Sambat API, or Nepali datepicker regression suite.
Software-agent and MCP tool builders who need deterministic answers with proof receipts instead of guessed dates.
Auditors and maintainers who need source notes, not broad claims.
