An anytime planner that reads like your own placement sheet, but the festival columns fill in automatically from the daily festival calendar.

Setting Date = Placement Date − incubation days (default 21, editable).
Placement Date = each day of the month you pick.
Festival Date (sale window) = Placement Date + grow-out days — set this at the top (default 42; presets 28/35/39/42/45 or type any 14–90). The day the birds are ready to sell.
Festival Name & Day = looked up on that sale date from the calendar (2016–2029).

Change the grow-out days and everything downstream recomputes — sale date, festival, weekday, colour, the summary and the rate history all follow. Your choice is saved on this device.

Colour = demand signal. 🟥 Sell into it — the sale lands on (or within 3 days of) a high-demand festival (Ganesh, Navratri, Diwali, Eid, Dussehra…). 🟨 Avoid landing here — a soft window (Shraddha / Pitru Paksha, Shravan, Adhik maas, dry days) when non-veg demand dips. ⬜ neutral.

📈 rates on any festival row shows the broiler selling rate (SK Patel big-bird) two ways over the last 5 years: on the same calendar date, and on the same festival (which shifts date each year) — with each year's rate marked against that year's production cost (green = above cost). Hatching Egg and Chick rate columns show the actual rate on the setting/placement date from your rate files (blank where not filled).

🔒 Lock production cost uses the same model as the What-If Lab — set body weight, mortality, FCR, feed ₹/kg and the per-bird costs (chick, med, admin, o-head) plus GC ₹/kg, and it computes your cost ₹/kg (per-bird costs ÷ saleable kg, where saleable = body wt × survival). The profitability table then measures each festival's expected selling rate against that locked cost → margin ₹/kg, profit ₹/bird and a GO / THIN / SKIP call, so you can see at a glance whether the week or month pays. The dashboards below (at-a-glance mix, expected festival rates, best windows, next-6-month outlook) all follow the same live logic. The demand tiers are a starting convention and can be adjusted.
