Forked from Moon Calendar 2024

This visualization presents a year-long moon calendar for 2020, showing each day’s lunar phase as a small orthographic projection of the moon arranged by month and day. User clicks trigger an animated red ring that expands and fades around the current day’s moon. The code uses D3 v5 with SVG, `d3.geoPath` and `d3.geoOrthographic` for rendering, and computes phases from a simple formula based on a fixed new moon reference time. Axis labels are generated with `d3.axisLeft` and `d3.axisTop`.

AI-generated description

Moon Calendar 2020

The Moon Calendar 2020 displays the moon’s phase for every day of the year in a grid, with months on the y-axis and days on the x-axis. Each moon is rendered as an orthographic projection of a circle using `d3.geoPath` and `d3.geoOrthographic`, with phase computed from a simple lunar-cycle formula. Clicking anywhere highlights the current day’s moon with a fading red ring, animated via `transition`. The visualization uses `d3.scaleLinear` for days, `d3.scalePoint` for months, and `d3.timeDays` to generate the date sequence.

Moon Calendar 2022

A grid of small moon icons displays the lunar phase for every day of 2022, with months arranged along the y-axis and days along the x-axis. Each icon uses an orthographic projection with `d3.geoPath` and `d3.geoCircle` to render the illuminated portion based on a “Simple” phase calculation. Clicking anywhere on the chart animates a red ring around the current day’s moon via an SVG transition. The visualization is built with D3 v5, uses SVG for rendering, and derives its phase values from a fixed reference new moon timestamp.

Fork of Moon Calendar 2021

This visualization displays the moon’s phase for each day of 2021, arranged as a calendar grid with months on the vertical axis and days on the horizontal axis. Each moon is rendered via `d3.geoPath` and `d3.geoOrthographic` with circles and paths showing the illuminated portion based on a simplified lunar phase calculation from ben-daglish.net. Clicking anywhere on the SVG animates a red ring to highlight the current day using a `transition` with duration and stroke attributes, while axes are built with `d3.axisTop` and `d3.axisBottom`.

Fork of Moon Calendar 2022

This visualization displays a full year of moon phases as a calendar grid, with months on the y-axis and days on the x-axis. Each day renders a small moon using d3.geoPath and d3.geoOrthographic, with phase computed from a simple lunar period calculation based on a 1970 reference new moon. A click on the visualization adds a red pulsing ring around the current day’s moon via a transition. The code uses d3.timeDays and d3.axis scales to layout the calendar, with SVG animation for the highlighting effect.

Fork of Moon Calendar 2022

This visualization displays the moon’s phase for every day of the year 2022 in a calendar grid, with months on the y-axis and days on the x-axis. Each moon glyph is drawn using `d3.geoOrthographic` and `d3.geoPath` to project a circle based on the phase angle, calculated from a simple lunar period formula. The SVG renders a dark circle with a light path overlay to represent the illuminated portion. Clicking the graphic triggers an animated red ring that expands and fades to highlight the current day.

Moon Calendar 2017

A 2017 moon calendar renders each day as a small orthographic projection of the Moon, showing its phase across the year in a grid of months and days. Clicking the visualization highlights the current day with an animated red ring. Built with D3 v4, it uses `d3.geoPath` and `d3.geoOrthographic` to draw each moon, with phase angles calculated from a lunar period formula derived from a known new moon epoch. The SVG output is organized using `d3.scaleLinear` and `d3.scalePoint` for axes, and dates are generated via `d3.timeDays`.

Moon Calendar 2024

The Moon Calendar 2025 renders each day of the year as a small orthographic projection of the Moon’s phase using d3.geoPath and d3.geoOrthographic. Days are arranged in a grid by month along the y-axis and day of month on the x-axis, with axes labeled via d3.axisTop and d3.axisBottom. The phase is computed from a simple lunar period formula using timestamps. Clicking any point triggers a red expanding circle animation via transition, highlighting today’s position.

Moon Calendar 2022 - a bit off.

A lunar calendar for 2026 displays each day as a small moon phase, arranged by month on a grid, with a red circle animating to highlight today’s date on click. Phases are computed from a reference new moon using a fixed lunar period and mapped via `d3.geoOrthographic` and `d3.geoPath`. The visualization uses `d3.timeDays` for daily data, `d3.scalePoint` for months, and D3 transitions for the click interaction.
