Event window inputs

Enter the cycle you observed between two windows and how long ago the last one passed. Nothing is prefilled, because different events run on different cycles.

How to use the countdown

Watch one full cycle: note when a window opens, then note when the next one opens. That gap is the cycle. Enter it together with how long ago the last window passed.

The planner returns the countdown, the clock time of the next window, and the clock time two cycles after that, so you can plan a session around more than one opening.

Why nothing is prefilled

Rare-egg windows, rifts and Admin Abuse do not share one cadence, and the game publishes no universal timer. A default would be a claim this site cannot support.

Re-measure after a restart or a big update. Either can reset the cycle, and a stale offset would put your countdown in the wrong place.

Formula & limits

Next window incycle − (time since last window mod cycle)
Next window atyour device time + the countdown
Third window atnext window + two further cycles

The countdown follows your own device clock, so treat it as a session aid rather than a server schedule. A server restart resets the cycle, so re-measure after one.

FAQ

Where does the cycle length come from?

From your own observation of two consecutive windows. Different events run on different cycles, and the game publishes no single universal timer.

Why is the cycle not prefilled?

Because a filled-in default would be a claim this site cannot support. Community reports describe different intervals for different events, so the value stays yours.

Does the countdown follow server time or my time?

It follows your own device clock. Use it as a planning aid for your session and re-check in-game when a window matters.

What if my server restarted?

Re-measure after the restart. A restart resets the cycle, so the previous offset no longer describes where you are in it.
