Terms of Sale

What you are buying

One purchase of the 2027 moon calendar, for 9 US dollars plus any tax that applies where you are, gives you all of the following:

• A print-quality PDF calendar for the whole of 2027, computed for coordinates you choose and typeset for printing: a cover and twelve month pages, each showing moonrise, moonset, the phase and the illuminated percentage for every day, in the time zone you chose.
• The same calendar in an astrophotography edition, which adds each night's moonless dark window and the month's galactic core visibility. Both editions are included; you may download either or both.
• A calendar feed you can subscribe to in Apple Calendar, Google Calendar, Outlook or anything else that reads an iCalendar subscription, carrying the phases, supermoons and eclipses of 2027.
• The right to regenerate all of the above for a different location, as many times as you like, until 1 February 2028.

It is a digital product. Nothing is shipped, and no physical calendar is included. You print it yourself if you want it on paper.

Who you are buying from

Payment is taken by Stripe on a page Stripe hosts, and Stripe is the merchant of record for the sale. Stripe is the seller on the transaction: it takes the payment, calculates and remits any sales tax, VAT or GST due where you are, issues your receipt, and handles refunds and chargebacks. Your card details are entered on Stripe's page and are never seen by this site.

CycleCalcs LLC, a Virginia limited liability company, makes and supplies the product itself and is who you deal with about the calendar, its contents and its delivery.

Delivery and access

Delivery is immediate and electronic. When your payment completes you are returned to a page holding your downloads and your feed address. There is no account to create and no password to remember: the address of that page is your access, so bookmark it. It brings you back to your calendar any time until 1 February 2028.

Some payment methods settle through a bank rather than instantly. If you used one, that page will say so and tell you to return to it once the payment clears, which is typically a few days.

Treat your bookmark like a receipt: anyone who has it can download your calendar. If you lose it, email us from the address you paid with and we will send it back to you. The payment record is enough.

Refunds

If the calendar is not what you wanted, email info@cyclecalcs.com within 30 days of buying it and we will refund you in full. You do not have to give a reason, and there is nothing to return. This is a nine dollar calendar and we would rather you had your money back than felt stuck with it.

Stripe may also issue a refund directly in some circumstances, and applies any consumer protection rules that apply where you live, including statutory cancellation periods. Those rights are yours regardless of anything above.

What you may do with it

The calendar is for you. Print it as often as you like, for as many walls as you like, at home or at work. Give a printed copy to somebody.

What is not included is the right to redistribute the file itself or to resell it: do not post the PDF for download, share your access link publicly, or sell copies.

The astronomical values printed on the calendar are not owned by anybody. Under the site licence, every computed astronomical value CycleCalcs publishes is dedicated to the public domain, so the times and phases themselves are free for you to use for anything, including commercially. The reservation above is about the typeset document and its design, not about the numbers in it.

Place names and coordinates come from GeoNames (geonames.org) under CC BY 4.0, and the credit line printed on the calendar satisfies that condition. Leave it in place if you redistribute anything derived from it.

Accuracy

Every time on the calendar is computed for the coordinates you chose by the same engine behind every tool on this site (the method is public), and the calendar prints the time zone it used. Rise and set times are given to the minute and are typically accurate to about that.

They are geometric predictions of where the Moon is, not promises about what you will see. Terrain, weather, buildings and unusual atmospheric refraction all affect when the Moon actually appears over your horizon, and the calendar assumes a sea-level horizon. Do not rely on it where being wrong by a few minutes would be dangerous or costly: it is sold for interest and planning, and it comes with no warranty beyond the refund above.

Changes and availability

The 2027 calendar is sold until the end of 2027 and remains regenerable by anyone who bought it until 1 February 2028. Prices and these terms may change for future purchases; the terms that apply to you are the ones published when you bought.

The free preview, the free calculators, and the API's free tier are not affected by any of this and stay free.
