The official tomato record does not store a day count or a spacing. The pot size and the calendar day count are farmer field notes. Check both before you treat a number as a department figure.

Nursery months and rain-shelter wording
Tomato's stored wet-zone windows are nursery periods. Capsicum, on the same wet-zone list, has a year-round window whose note mentions irrigation or rain shelters. That sentence is shown only because it is stored on the capsicum window. It is not copied onto tomato.
Official planting windows
Tomato · Low Country Wet Zone
March · nursery_mid_march · transplant
HORDI says the suitable nursery period is the middle of March. The grid marks all of March because a month is the finest step. The same page gives an optimum elevation of 1000-2000 m and also says the crop can be grown in almost all agroclimatic zones except the up-country wet zone. Colombo is not named.

Sweet pepper · Low Country Wet Zone
No month pair is stored. · year_round · transplant
HORDI says capsicum can be cultivated in most agro-ecological zones throughout the year, with supplementary irrigation in dry periods. The same Planting section also lists Yala as April and May and Maha as November and December, and says it can be cultivated throughout the year under irrigation or rain shelters. Those two pairs are not stored as extra windows because the year-round statement already fills every month.
