Map a month of Instagram content to the batch-shoot days you actually have, not an idealized daily grid

You are building a one-month Instagram content calendar for a creator, and the starting constraint is production capacity, not posting frequency — the calendar has to be built backwards from the actual shoot days available this month, not forward from an ideal posting cadence that assumes unlimited time to produce content.

SHOOT DAYS AVAILABLE THIS MONTH
4 shoot days this month, each roughly a Saturday.

CONTENT PILLARS
Studio process, finished-product reveals, behind-the-scenes mistakes, customer features.

FORMATS IN ROTATION
Reels, carousels, and single-image posts — no Stories-only content counted here.

RECURRING DATES OR LAUNCHES TO HIT
New glaze color drops on the 18th and must have a reel ready that morning.

HOURS AVAILABLE PER SHOOT DAY
About 3 hours per shoot day, including setup and teardown.

CALCULATE CAPACITY FIRST
Before assigning any post, calculate roughly how many pieces of finished content the stated shoot days and hours per day can realistically produce, given that a single shoot day typically yields multiple pieces (a carousel, a reel, and several photo posts) but not an unlimited number — state this capacity number explicitly and build the calendar to that number, not to a round posting target like 'one per day' that ignores it. If the fixed dates and content pillars together would require more output than the stated capacity supports, say so explicitly and propose what to cut or combine rather than quietly overcommitting the calendar to more posts than the shoot days can produce.

BUILD THE CALENDAR
Assign each planned post to the specific shoot day its raw material would come from, not just to a calendar date — a post scheduled for the 14th but shot on the 3rd should show both dates, so the creator knows when to actually capture it. Rotate through the stated content pillars and format mix so no single pillar or format repeats more than twice in a row. Place fixed dates and launches on their exact required day, then build the rest of the calendar around them, not the other way around.

OUTPUT FORMAT
A table with columns: Post Date | Shoot Day | Content Pillar | Format | Working Title/Hook | Notes. Precede the table with the calculated realistic capacity number and one sentence stating whether the requested output fits inside it. Follow the table with a short list of anything cut or combined to make the plan fit actual capacity.
