About

Dealcalendar is a fully local worldwide shopping-event calendar. calendar_overview lists every event covered. event_info gives one event's full detail and origin. dates_for_year computes or looks up an event's date(s) for any year — fixed-formula events (Black Friday, Cyber Monday, Cyber Week, Green Monday, Singles Day, the 618 festival, Boxing Day) are computed live and work for any year past or future; Amazon Prime Day, Amazon Prime Big Deal Days, and Diwali sales come from a verified historical table and this tool says plainly when a requested year isn't yet known rather than guessing. next_occurrence and days_until find the next time an event happens. historical_dates returns the full verified year-by-year table for a retailer-announced or lunar-calendar event. all_events_for_year lists every event's date(s) for one year, chronologically. search_events and events_by_region filter the catalog. Fixed-formula dates are computed from well-documented calendar rules and reliable for any year; historical-table dates are verified as of the build date. Keyless; fully local; zero upstream calls; nothing stored.

Sources: Fixed-formula events (Black Friday, Cyber Monday, Cyber Week, Green Monday, Singles Day, 618, Boxing Day) computed live from their well-documented public calendar rule. Amazon Prime Day, Prime Big Deal Days, and Diwali dates verified via public reporting and official/public holiday references as of build date (September 2026); years beyond the verified table are marked unconfirmed rather than guessed.

What Deal Calendar is for

"When exactly is Black Friday this year?", "when's the next Prime Day?", "what date was Diwali in 2024?" — a worldwide shopping-event calendar that actually computes or verifies its answers instead of vaguely gesturing at "usually around November."

What it does

calendar_overview lists every event covered: Black Friday, Cyber Monday, Cyber Week, Green Monday, Singles Day (11.11), China's 618 mid-year festival, Boxing Day, Amazon Prime Day, Amazon Prime Big Deal Days (the October sale), and India's Diwali sales season. event_info gives one event's description, region and origin story. dates_for_year is the core tool — for fixed-formula events (Black Friday, Cyber Monday, Cyber Week, Green Monday, Singles Day, 618, Boxing Day) it COMPUTES the real date from the event's well-documented calendar rule, so it works correctly for any year, past or future. For retailer-announced events (Prime Day, Prime Big Deal Days) and the lunar-calendar Diwali, it looks up a hand-verified historical table — and if you ask for a year beyond what's confirmed, it says so plainly rather than guessing. next_occurrence and days_until find the next time an event happens from today or a given date. historical_dates returns the complete verified table for a retailer-announced or lunar event. all_events_for_year lists every event's date for one year, chronologically. search_events and events_by_region help you browse by keyword or region.

What it is not

Fixed-formula dates (Black Friday and friends) are computed from real, well-documented calendar rules and are as reliable as a calendar for any year. Amazon's own sale events and Diwali's date are not on a fixed formula — Amazon announces Prime Day's dates itself each cycle, and Diwali follows the Hindu lunar calendar — so this tool only reports years it has actually verified, and is explicit when a future year isn't confirmed yet rather than inventing a plausible-sounding date.

Deal Calendar — Privacy Policy

Effective 25 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Deal Calendar is. Deal Calendar is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for a worldwide shopping-event calendar — Black Friday, Cyber Monday, Singles Day, Amazon Prime Day, Diwali sales, Boxing Day and more, computed from real calendar rules or verified against public reporting. You interact with your assistant; the assistant sends us only the arguments needed for that one lookup.

What we receive. The arguments of each tool call, the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Everything is answered from a bundled, hand-curated reference file and nothing is stored. No request is forwarded to any third party — there is no upstream call at all, live or otherwise — and no query is logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant or your name, and we do not build a profile from your queries: each request is answered independently and nothing carries over between requests. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. None — the entire dataset is bundled with the server and answered locally. Hosting: Vercel (United States regions).

Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Deal Calendar is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.

Deal Calendar — Terms of Service

Effective 25 September 2026. These terms govern use of the Deal Calendar connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

  1. The Service.

It is accessed through an AI assistant or directly over MCP or HTTP.
  2. General information, not professional advice. Deal Calendar provides general, hand-curated reference information. It does not know your specific product, purchase, brand, or situation, and it is not a substitute for reading the manufacturer's or retailer's own materials, or for professional advice where relevant.
  3. Reference, not guaranteed-current. Content reflects general, widely published practice as of the build date stated in the Service's own data. Some figures, dates or rules change over time and vary by brand, retailer or region — always verify anything decision-critical against a primary source.
  4. Acceptable use. Automated use within the published rate limits is welcome.
  5. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
  6. Data. Our Privacy Policy describes what we process. In short: your query is answered from a bundled reference file, and nothing is stored.
  7. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
  8. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss, injury, or damage arising from use of, or reliance on, the Service. Our total liability is limited to US $100.
  9. Governing law. California law; venue in San Mateo County, California.
