Built for a quick check before you fly.

The live tools appear first. The explanation stays here when you need it.

SkyCOTL.tools converts repeating events from Sky Mean Time to the timezone reported by your browser. Shard results use a community prediction rule and are clearly labelled when they can change.

Nothing here requires an account or a backend. Countdown, shard and calculator logic run on your device.

Sky COTL tools for the decisions players make every day

SkyCOTL.tools is a fan-made toolkit for Sky: Children of the Light. Each page answers one practical question first, then explains the timing rule or estimate so you can judge the result instead of treating it as an official promise.

Use Sky Clock to catch Geyser, Grandma and Turtle

Sky's repeating wax events are easy to miss when a schedule is written only in Pacific time. The live Sky Clock anchors the event cycle to Sky Mean Time, detects the timezone reported by your browser and displays the active or next event with a local start time and countdown. It also keeps Daily Reset visible, because reset time affects quests, seasonal tasks and the beginning of a new candle day.

Open the full clock when you want to compare the whole two-hour run. Geyser begins near :05, Grandma near :35 and Turtle near :50 in the repeating cycle. The event location stays beside the time, so the clock helps you decide whether there is enough travel time before entering a realm. Optional browser reminders are requested only after you choose one; they are not an account or a server notification service.

Check Sky Shards with the prediction evidence visible

The shard tracker answers the immediate question—whether a red shard, black shard or no shard is predicted today—then shows the realm, location, reward type and available windows. Times are converted for the current browser timezone. You can move to another date when planning ahead, or use the location guide when a place name is unfamiliar.

Shard schedules are community predictions rather than official announcements. The page labels that boundary and shows the rule evidence used for the result. A game update can change a rotation, so the tracker should help you plan, not persuade you that an unverified prediction is guaranteed. Longer official seasons and special events live in the separate Sky Events Calendar with links back to their announced sources.

Plan candle goals with inputs you can change

The Sky Candle Calculator supports four different planning questions: how long a regular-candle goal may take, whether a seasonal target fits the remaining days, how Eden and red-shard income may affect an ascended-candle goal, and whether current balances cover a Traveling Spirit tree. These are separate modes because one fixed formula cannot honestly describe every Sky currency.

Your balances, target and earning rate remain editable. The calculator does not claim to know how long you play, which route you run, what a future Spirit costs or how many rewards you will collect. It produces a planning estimate from the values you enter and saves those values only in this browser, making it useful for comparing a conservative plan with a more ambitious one.

Keep longer events in the calendar you already use

The Sky Events Calendar combines reviewed official date ranges for seasons, Traveling Spirits and special events with clearly labelled community shard predictions. On a wide screen it provides a month view; on a phone it uses an agenda so names and actions remain readable. Filters help separate official events from predictions without hiding the source boundary.

You can download an individual calendar file or subscribe to a continuing feed for wax events, Daily Reset and shard predictions. A subscription is free and does not create a SkyCOTL.tools account. Calendar software decides how often a feed refreshes, so the website also keeps the current result available for a last check before you fly.

Practise Sky music without sending a song file away

The Sky Music Keyboard keeps the familiar 3 × 5 note layout and works with touch, computer keys or supported MIDI input. You can play a phrase immediately, record note timing, slow the practice speed and follow a falling-note track. The tool can also read common Sky sheet JSON structures when you choose a file.

Selected sheet files are parsed locally in the browser and are not uploaded to this site. The practice export contains note and timing data rather than microphone audio. This privacy-first approach is shared across the toolkit: no sign-up is required for the core tools, and the site avoids pretending that a fan-made schedule, prediction or practice file is an official game feature.

A quick check before a Sky session

You do not need to read every guide on every visit. Start with the live answer and open only the planning tool that changes what you will do next.

  1. Read the next event

    Check the live countdown and location. If the event is already active, compare the remaining time with the travel route before entering a realm.

  2. Confirm today's shard

    Look for the predicted shard type and window, then open the evidence when a game update or player report suggests that the rotation may have changed.

  3. Choose a realistic goal

    Use the candle calculator for a specific target, or the events calendar for a deadline. Adjust your earning rate instead of relying on a maximum-run promise.

  4. Return to the game

    Bookmark the exact tool you use most. Local time conversion and browser-only saved values make the next check shorter without requiring an account.

SkyCOTL.tools questions

What the tools do, where their limits are and how your data is handled.

What are Sky COTL tools?

Sky COTL tools are fan-made utilities for recurring event times, shard predictions, candle planning, calendar reminders and music practice in Sky: Children of the Light. This site groups those tasks while keeping each tool on a focused page.

Is SkyCOTL.tools official?

No. SkyCOTL.tools is a fan-made utility and is not affiliated with thatgamecompany. Official date claims on the events calendar link to reviewed announcements; shard results are labelled as community predictions.

Does Sky Clock use my local timezone?

Yes. Sky Clock keeps event rules anchored to Sky Mean Time and converts the result to the timezone reported by your browser. It also displays the detected timezone so you can notice a device setting that looks wrong.

Are Sky shard times guaranteed?

No. Shard results use a community prediction rule and can change after a game update. The shard page shows the prediction status and supporting rule so you can recheck uncertain days.

Do I need an account or subscription?

No. The core clock, shard tracker, candle calculator, calendar and music practice tools are free to use without signing up. Calendar subscription means adding a free feed to your calendar app, not buying a plan.

What data does SkyCOTL.tools upload?

The core tools do not upload your calculator values, chosen music files or recorded note phrases. Those tasks run in the browser. Anonymous aggregate events may measure whether a page or tool is used, but they do not include account or game-login data.
