A holiday and seasonal calendar is a Skill job you finish in an afternoon: one brief, one twelve-month map, and an hour or two of checking. You give ChatGPT or Claude your services, your town, your customers and your busy and slow months, and it maps the year ahead to the holidays, seasons and local moments that fit what you sell. This page covers the year-ahead map: which moments matter to your business, and when to start talking about each one. The month-by-month post plan belongs to the free content calendar template, which turns the month in front of you into planned posts. The map tells you what is coming, and the template fills in each month as it arrives.

The shape: Skill
A Skill job is a brief you write once and reuse. You paste one prompt, you get one answer, and your judgment does the rest. You connect nothing to the AI and build no system.
This job fits the Skill shape because most of the work is sorting and matching. There are hundreds of holidays, observances, shopping days and awareness days in a year. An owner who sits down with a blank calendar usually remembers the big ones and forgets the moments that actually move their trade, such as the first cold week, the start of the school year or the run-up to tax day. The AI can lay the whole year out at once and match each moment to a service, which is the step that takes a person hours.
The limit of the shape matters just as much. The AI does not know next year's dates for certain. Holidays that move, such as Easter, Lunar New Year, Ramadan, Passover and Diwali, land on different dates each year, and an AI can state the wrong one with full confidence. It also pads lists with awareness days that are hard to trace to any real source. It knows nothing about your town's own calendar: the street fair, the high school graduation weekend, the week the snowbirds arrive. So the job splits in two: the AI drafts the map, and you check every date and add the local moments only you know.
What this means for you: treat the AI's map as a first draft of the year, never as a finished calendar. The value is in the sorting. The accuracy comes from you.
What you give the AI
The map can only be as specific as what you tell it. Give it these, by name, in one message:
- Your services, in the words customers use. "Furnace tune-ups, AC repair, duct cleaning" beats "HVAC services".
- Your town and region, and the climate in a phrase: "Phoenix, very hot summers, mild winters" changes the whole year.
- Who your customers are, in one sentence: "families with young kids who book a few weeks ahead".
- Your busy months and your slow months, from your own records or your memory of last year.
- What customers ask for at each time of year, even rough: "everyone wants gift cards in December", "nobody books in August".
- Local events you take part in or that bring people to your street: a farmers market, a festival, a home show, a race.
- Dates already fixed on your own calendar: your anniversary, a planned closure, a price change, a new service launch.
- The cultural and religious holidays your customers observe, if they shape when people buy or close up shop.
- Days you never want to post about, such as anything that would read as tone-deaf for your trade.
- The platforms you post on, so the AI can note where a moment fits best.
If you work in a regulated field, such as health, finance or law, say so in one line. Seasonal offers in those fields carry rules about claims and promotions, and the AI should flag any it suggests.
What comes back
You get a twelve-month table, one row per moment, with the date or date range, the reason it matters to your business, the service it connects to, and when to start posting about it. You also get a short list of dates the AI is unsure about, and a list of popular days it left out on purpose, with the reason.
Paste this brief into ChatGPT or Claude, with your inputs below it:
Build a twelve-month holiday and seasonal calendar for my business, starting [month and year].
Rules:
- Include three kinds of moments: fixed holidays and shopping days, seasonal shifts in my trade (weather, school year, tax season and similar), and the local events I list.
- Only include a moment if it connects to a service I offer or to when my customers need me. Say the connection in one plain sentence.
- For each moment give: month, date or date range, name, why it matters to my business, the service it ties to, and a "start posting" date (how many weeks before).
- Mark every date that moves from year to year as "check date". Do not guess silently.
- Mark any awareness day you cannot tie to a well-known source as "check source", or leave it out.
- Mark my busy months and slow months. In slow months, suggest moments that help me fill the calendar, not just holidays.
- Never include a day from my "never post" list.
- After the table, list up to ten popular days you left out on purpose, with one line each on why.
- Finish with a three-column list I can paste into a spreadsheet: date, moment, status (all "unchecked").
My services, in customers' words:

My town, region and climate:

Who my customers are:

Platforms I post on:
[list]The last part of the answer is a list you can paste straight into a spreadsheet, so the map can live beside your other plans. If the first answer is long, ask the AI to cut it to the twenty or thirty moments with the strongest link to your business.
How to judge it
Read the map once, top to bottom, with your own year in mind. A bad map is easy to spot.
- It is a list of national holidays and nothing else. A good map has your weather, your school year and your busy season on it, not only the days on a printed wall calendar.
- Most rows have a weak connection. "National Pizza Day" on a dentist's calendar, or a reason that says "a great chance to engage your audience", means the AI matched nothing.
- Moving holidays carry a confident date with no flag. Check those first, because they are the most likely to be wrong.
- Awareness days you have never heard of fill the gaps. Some are real, many are not, and none of them earn a place unless you can find the source.
- The start-posting dates are all the day itself. Most seasonal posts work best before the moment, when customers are still deciding.
- The slow months are empty. Those are the months a map should help most.
- It ignores your climate or region. A spring cleanup post in February makes sense in some places and none in others.
A good map is shorter than you expect, has a clear reason on every row, and has your trade's seasons on it in your own words. If you would not post about a moment, delete the row.
What stays with you
The AI sorts the year. These parts are yours.
Every date gets checked. Look up each moving holiday and each awareness day against an official or well-known source before it goes on your calendar. A post that wishes people well on the wrong day is the post people remember.
The local moments are yours. The street fair, the school calendar, the week your town floods with visitors, the month your main employer closes for maintenance. No AI knows these, and they are often the moments that bring the most customers.
Your own business calendar is yours. Planned closures, staff vacations, price changes and new services only you know about. Put them on the map yourself.
The judgment on sensitive days is yours. Some days call for silence or a short, sincere note, not a promotion. Decide those case by case, for your business and your customers.
The posts themselves are a separate step. The map says when. Writing each post, with your real work and your real hours, happens month by month. For the writing, our note on what to post around holidays without sounding generic covers the habits that keep holiday posts from reading like everyone else's.
An example (invented business)
Say you run a two-person landscaping company in a town with cold winters and a long, wet spring.
You give the AI your services (spring cleanup, mowing, mulch, fall leaf removal, snow plowing), your town and climate, your customers ("homeowners on half-acre lots who want the yard handled"), your busy months (April to June, October, and any snowy week), and your slow month (late January). You add the local garden club's plant sale in May and the town's fall festival in October.
The map that comes back puts spring cleanup reminders in early March, weeks before the first warm weekend, and mulch in April. It ties Memorial Day weekend to "yard ready for the first cookout" and late summer to booking fall leaf removal early. It flags the first frost window as "check date" for your area and puts snow plowing sign-ups in early November. It suggests using late January for posts about planning next year's yard, since the phones are quiet. It also leaves out a stack of food and novelty days, with one line each on why they have nothing to do with yards.
You check the frost date against your local extension office, add the plant sale and the festival, and delete two rows that felt like a stretch. The map is done in an afternoon. Each month, you open it, see what is coming, and plan that month's posts.
This is an editorial example, not a customer.
A full year map or one season at a time
| If this is you | Build |
|---|---|
| Your business has strong seasons and a clear busy time | The full twelve-month map, so the busy season never sneaks up on you |
| Your year is fairly even, or you are new and do not know your seasons yet | One quarter at a time, then extend it as you learn |
| You already plan posts each month and keep missing key dates | The full map, used only as a reminder list beside your monthly plan |
For the quarter-by-quarter version, our note on planning a quarter of content around customer timing walks through it. For the weather side of the map, see how to turn weather, timing and service windows into useful posts.
Where the map goes next
Save the checked map in a spreadsheet, and set a reminder for the first of each month to open it. At that point the month in front of you becomes a post plan, and the content calendar template is the next step. Run the same brief again once a year, a month or two before January, with last year's map attached, and ask the AI what to add, move or drop.
