Your Eclipse Day: August 2, 2027, timed for your exact spot
The century's longest land totality crosses southern Spain, North Africa and the Arabian Peninsula: up to 6 minutes 27 seconds of darkness near the center line in Egypt, while at the edge of the path a few kilometres decide between real darkness and none at all. This document computes your morning to the second, for the coordinates you actually stand on.

The samples are the real documents for the spot you picked, watermark aside, and the verdict above runs in your browser on the same engine that computes them. The free town-by-town pages show the full method in public.
What the document is
Your contacts, to the second
First bite, totality begin and end, maximum and last contact (the five contacts, as astronomers call these instants), each in your local clock and UTC, with the Sun's altitude and compass direction at every one, plus which way the shadow arrives and how fast.
A minute-by-minute plan
From forty minutes out to the final second: when the light turns strange, where to look, when filters stay on and the one window they come off. Printed to be taken outside, away from screens and signal.
A calendar file that fires
The eclipse lands in your calendar app with alarms attached, from the day before down to the final minutes, timed for your coordinates rather than a city near them. Apple Calendar fires them as written; Google and Outlook apply their own reminder rules.
Margin matters as much as timing, so the document also computes how far you are from the edge of the path, what a short drive toward the center line buys, and the nearest towns with full free pages. The method is the one behind every tool on this site.
What nine dollars buys
- The three-page plan. Verdict, contacts to the second with the Sun's position at each, and the morning script.
- The field card. A one-page large-type version for a pocket or a clipboard, made to be read in falling light.
- The alarmed calendar file. Events with alarms attached, timed for your coordinates.
- Every spot you are considering. Regeneration is unlimited until 1 October 2027: compute the hotel, the beach and the backup hill, and compare them.
- The margin check. How far you stand from the edge of the path, and what a drive toward the center line buys, computed rather than guessed.
- The shadow's approach. Which horizon darkens first and how fast it comes, from the local timing gradient.
- The fallback plan. The nearest computed towns with distance and bearing, each with a full free page to hand to the rest of the car.
Questions a careful buyer asks
What exactly do I get for $9?
Three files, delivered the moment payment confirms, all computed for the coordinates you picked: a three-page printable plan (the verdict for your spot, every contact time to the second with the Sun's altitude at each, a minute-by-minute plan for the morning, the shadow's direction and speed, your margin to the edge of the path, the nearest computed towns and the eye-safety rules), a one-page field card in large type for a pocket or a clipboard, and a calendar file whose events carry alarms: the day before, an hour before and again ten minutes before first contact, and, where your spot has totality, fifteen and two minutes before it.
What if my plans move?
Regenerate, free, as often as you like: one purchase covers any coordinates until 1 October 2027, and the final choice of viewing spot is often made on eclipse morning. Your download page takes a new place and rebuilds all three files in seconds.
What if my spot turns out to have no totality?
The document says so, honestly, before you travel: it states the partial percentage, that filters never come off there, how far the edge of the path is, and how much totality a drive past that edge buys, computed at three real distances along your meridian. The free preview above gives the same verdict before you pay.
How accurate are the times?
Contact times are computed for your exact coordinates at sea level with a mean lunar limb (the Moon's average edge, ignoring its mountains and valleys) by the same open-source engine behind every page on this site; lunar limb corrections shift the start and end of totality by a second or two either way. Moving a few kilometres matters more than any correction, which is why the document also computes your margin. The method and its measured accuracy against JPL Horizons are public at methodology and accuracy.
Do I need an account?
No, and there isn't one to create. After paying you land on a page holding all three files, and that page's address is your private link back: bookmark it and you can download again or regenerate for different coordinates any time until 1 October 2027. If you lose it, email info@cyclecalcs.com from the address you paid with and we will send it back.
What about clouds?
No document can move them, and this one does not pretend to: it contains no weather data, only geometry and time. What it gives you against clouds is mobility. Regeneration is free for any coordinates until 1 October 2027, so when the forecast firms up in the final days you can recompute the plan, the field card and the alarms for wherever the sky looks best and drive with numbers rather than guesses. The free town pages each carry a short August climatology note.
