Enter each member's march time and the impact time. Get who sends first, the exact send clock for each march, and a copy-ready call order — so marches land together or a few seconds apart. Free, no login.
Leave the impact time empty to get countdown offsets only (T-minus).
March times depend on distance, troop type and active speed buffs — read each one from the game's march screen right before you send. This page only does the subtraction; it does not read the game, and every march is still sent by hand. Clocks are UTC.
When several members attack or reinforce one target, the order they press send matters more than how fast they are: a short march sent too early arrives alone. The rule is one subtraction — send time = landing time − march time. The longest march therefore goes first and the shortest last. This planner applies that to your whole list at once and sorts it into a call order you can paste into chat.
