First identify which deadline has closed

On Winter 22, Rainbow Chard's six-day growth period lands exactly on Winter 28. Move the planting to Winter 23 and its first date becomes 29, outside this plan. You have lost the last ordinary start for Chard in Winter. That is a crop-specific deadline, so it does not yet answer whether any other planting can meet a day-28 target.

Use the remaining day deliberately

Lettuce needs four initial days and is listed for Winter. A Winter 23 start gives Winter 27. Waiting until Winter 24 gives Winter 28: there is one more day on which you can start Lettuce and still meet the end-of-season calculation. This is one day of planting flexibility, not one day left in the season and not an extra harvest round.

Choose Winter 23 if you want the calculated date before the final day. Choose Winter 24 only with the understanding that the ideal schedule has reached its boundary. If your actual need is Chard, Lettuce is not a replacement for that requirement. It is an alternative only when the decision is about finding a crop that can still reach a first harvest in this window. The earlier Lettuce start leaves one calendar day after its listed harvest. That margin distinguishes the choices even though each has one round; it is not a modeled allowance for missed watering or delayed harvesting.

  • Chard on Winter 22: one date, Winter 28.
  • Chard on Winter 23: no date within Winter.
  • Lettuce on Winter 23: one date, Winter 27.
  • Lettuce on Winter 24: one date, Winter 28.

Neither crop has a repeat interval to rescue a late start

Both records are single-harvest crops. Once their first date fits, the date list is complete for that planting. There is no short regrowth interval to add, and making the bed larger cannot shorten the first wait. The four scenarios keep twelve plants as the input so the changed crop or starting day is what explains the changed dates.

Rainbow Chard's visible Vegetable label follows the structured item tag; Plants and some Wiki labels instead say Root. The sources agree on six growth days and no regrowth, so the classification difference does not change this comparison. Lettuce's four-day, no-regrowth fields were checked against its specific item revision. Both cases remain public-source calculations under daily watering, normal fields and no growth modifiers. A final-day date assumes harvesting on time; the plan makes no prediction beyond Winter 28.

An empty window stops at day 28; it does not predict the plant’s fate afterward. Plant count is not produce yield. Source decisions and model limits.
