Month Notes
Priorities, appointments, bills, birthdays, school notes, travel plans and month-end reminders.
Assumptions
Gregorian calendar, local browser date rules, visible range 2026-08-31 to 2026-10-04, ISO weeks 36-40.
The sheet is calculated as a local Gregorian month grid
Each visible cell is built from browser JavaScript Date objects at local noon. The week-start setting changes the leading offset, paper controls change the printed sheet styling, and event lines mark matching ISO-style dates.
Print controls
A4 and Letter controls set page-size hints, while portrait and landscape controls change the print stylesheet. Browser print dialogs may still apply user printer defaults.
Counting rule
The month contains only dates whose local month matches the selected month. Leading and trailing dates are shown so the printed sheet keeps complete weeks.
Limits
This page does not infer public holidays, school terms, lunar events or legal deadlines. It is a blank planning sheet with user-entered events.
Source Notes
Standards and browser basis
Browser JavaScript Date objects provide the local Gregorian date grid, while ISO 8601-style YYYY-MM-DD values are used for event entry and visible assumptions. The paper-size controls are CSS print hints, not printer-driver commands.
