### 2.1.9 Calendar, Region, and Season Tracking Lock
Day Zero is locked to early summer on the shared calendar. All U.S. arcs share the same broad calendar, but weather and survival pressure differ by region.
Every part, block, and chapter brief must track:
1. month after Day Zero,
2. apocalypse year,
3. calendar se
### 2.2 World Period, Technology, Media, and Available Objects Lock
Day Zero takes place in a world roughly equivalent to 2003.
This is a global world lock, not only a detail of Part 4. It affects, from Part 1 onward, what characters know, how they communicate, what can be found in stores, vehicles, homes, warehouses
### 2.2.1 Day Zero Infrastructure Collapse Timeline Canon
This is a global canon lock for the whole saga. It controls electricity, water, landlines, mobile phones, television, radio, internet/news access, refrigeration, fuel pumps, sewer, and generator logic from Day Zero onward.
Core lock: infrastructure does not co
#### Locked timeline
1. **0-6 hours after Day Zero begins:** most infrastructure may still work partially in some places. Radio, television, landlines, mobile phones, water, electricity, emergency announcements, and early internet/news access can still exist, but overload and contradictory reports begin immediately.
2
#### Writing implications
1. Day Zero should not become silent too soon. Early collapse still has phones, radio, television, sirens, emergency voices, failed calls, and contradictory information.
2. The first week should feel like systems dying: flicker, weak faucet, warm refrigerator, failing dial tone, dead battery,
### 2.2.2 Light, Darkness, Weather, and Seasonal Survival Canon
This is a global canon lock for the whole saga. It controls night, artificial light, fire, temperature, rain, winter, heat, storms, seasonal planning, children, animals, intimacy, route movement, and shelter logic after infrastructure collapse.
Core lock
#### Locked night and light rules
1. After public power fails, most labor shifts to daylight: water, laundry, repairs, supply sorting, food, medical care, baby care, animal care, route checks, and vehicle work.
2. Night movement is never neutral. It requires a reason and must account for visibility, noise, footing, we
#### Locked weather and season rules
1. Winter threatens through cold, wet clothes, poor sleep, lack of heat, smoke risk, frozen or clumsy hands, infection, children, babies, animals, and the need for dry socks, blankets, hats, gloves, wind protection, and body heat.
2. Rain is both gift and threat. It provides water,
#### Character, child, animal, and intimacy implications
1. Weather affects relationships. Cold makes body heat practical and intimate. Heat makes patience thin. Rain can force shelter, waiting, washing, route changes, touch, or conflict.
2. Sex and intimacy do not disappear, but conditions shape them: privacy, smell,
#### Writing implications
1. Do not write a weather report. Write weather through body, object, route, clothing, watch positions, failed sleep, fire choices, water choices, and dialogue.
2. Do not let the group move through nights, storms, winter, heat, or mud as if conditions are decorative.
3. Do not give safe fire,
### 2.3 Body, Hygiene, and Water as Everyday Life Canon Lock
The saga takes place in a realistic living-dead world, so the characters are not TV-clean and not bodyless.
Hygiene is part of world canon, not decoration for a specific chapter and not a layer belonging only to Part 1.
Locked for all parts:
1. Water is a
### 2.4 Intimacy, Desire, Sex, and Smut Canon Lock
The saga is romantic fanfic with body, desire, sex, smut, and explicit smut when it fits the couple stage, character age, consent, physical space, and emotional state of the scene.
Locked for all parts:
1. Intimacy is not only a hint, a look, or a hand on a shoulder
### 2.5 Water, Food, Hunting, Fishing, Livestock, and Food Preservation Canon Lock
The world did not empty of food in one day. There is food in pantries, homes, stores, warehouses, kitchens, schools, gas stations, camps, bases, restaurants, farms, gardens, fields, vending machines, vehicles, fishing routes, hunting ar
## 3. Timeline and Ages
These are calculation locks. If an age, birth month, pregnancy, or time jump changes, this section must be updated before chapter planning continues.
### 3.1 Timeline and Ages
Central control document for timeline and ages.
This is internal working canon, not an attempt to copy screen canon ages from every series exactly.
The goal is to prevent time jumps, children frozen in one age, pregnancies that do not fit part length, and adults written as if time does not af
### 3.2.1 Macro Timeline Movement Lock, Pre-Writing Pass
The first major contact point is not Vauseman and not month 18. The first major meeting is Nancy / Robin / Lexa at approximately Month 16 after Day Zero.
Part 1 opens through Lexa's Day Zero and her sixteen-month survival route to the Shell radius / the moment
### 3.3 Base Ages on Day Zero
These ages are the calculation source. The age shown in text must be derived from them according to the plot month. If a character has no locked Day Zero age, or if born after Day Zero with no locked birth month, do not build an entrance chapter for them until it is locked here.

### 3.4 Rachel Pregnancy and Kurt Lock
* Rachel's pregnancy is seeded in Chapter 76, at the Vauseman wedding, around Month 25-26 after Day Zero.
* Part 4 lasts about half a year, Month 27 to 33. Therefore Rachel enters Part 4 around pregnancy month 1-2 and leaves it around month 7-8.
* There is no need to lengthen Par
#### 3.4.1 Kurt Name Source Lock, Finchel
* Finn and Rachel's baby Kurt is not named as an outside tribute to the series, but after Kurt Hummel.
* Kurt Hummel was part of Finn and Rachel's heart on Day Zero and in the first month afterward.
* Kurt dies in the first month after Day Zero, before Finn and Rachel leave fo
