Use this when the user wants a printable countdown calendar, a paper chain countdown, a "how many days until" calendar to cross off, a vacation or wedding countdown printable, an advent-style countdown to an event, or school days left until summer break. Pass event_date and event_name; start_date defaults to today in the user's time zone. Styles: grid (month pages with a big days-to-go number per box), chain (paper-chain strips, 10 per page) or tear_off (12 cards per page). weekdays_only counts Monday to Friday; skip_dates removes holidays. Returns the days-to-go numbers, the PDF, and an ICS file with all-day reminders at 100, 50, 30, 14, 7, 3 and 1 days to go and on the event day. Up to 400 days. Does not send notifications, set phone timers or count hours and minutes; not for a live countdown timer.
Date of the event, e.g. "2026-12-25". A date without a year ("Dec 25") means the next one after the start date.
"grid" (default: month pages with a big days-to-go number in each box to cross off), "chain" (paper-chain strips, 10 per page, one link to tear off each day) or "tear_off" (12 cards per page, one per day).
Optional short notes printed on the strips or cards in order, repeating if fewer than the days, e.g. ["Pack swimsuits","Read about the parks"]. Up to 80 characters each.
The user's IANA time zone for "today", e.g. "Europe/London". Default America/New_York.
"Letter" (default) or "A4".
Only for dates like 03/04/2027: "mdy" (US, default) or "dmy".

Days not to count, e.g. ["2026-11-26","2026-11-27"] for school holidays. Up to 120 dates.
First day of the countdown, e.g. "2026-11-01". Default: today in the user's time zone.
