Quarter Map

Q1: Jan-Mar · Q2: Apr-Jun · Q3: Jul-Sep · Q4: Oct-Dec

Notes

Annual goals, renewals, travel, audits, school blocks and family milestones.

Assumptions

Gregorian calendar, local browser date rules, monday week start, visible range 2026-01-01 to 2026-12-31.

Method

The year is built from local Gregorian date objects

Each visible date is created at local noon to reduce midnight daylight-saving edge cases. Leap-year status uses the Gregorian rule: divisible by 4, except century years unless divisible by 400. ISO week references use the ISO 8601 Thursday rule.

Year range

The browser control accepts years 1900 through 2100, covering ordinary planning without pretending to be a historical calendar converter.

Print path

The print button opens browser print. The print stylesheet hides controls and keeps the annual grid, summary, notes and assumptions.

Limits

Public holidays, school terms, fiscal rules and astronomy are not inferred here. Those belong on their own sourced calendar pages.

Source Notes

Standards and platform basis

The page uses the proleptic Gregorian calendar exposed by browser JavaScript Date objects and labels ISO week numbers using the ISO 8601 week-date convention where week 1 is the week containing the year's first Thursday.
