Detailed timeline of Mount Kilimanjaro and Map location

Key Geographic Details

Location of Mount Kilimanjaro

Climbing Mount Kilimanjaro is a journey through five distinct climate zones, and your experience depends heavily on matching your timeline with the mountain’s seasonal rhythms. About 50,000 visitors attempt the summit annually. 

Seasonal Visitor & Weather Timeline

The mountain follows a predictable cycle of dry and rainy seasons. 

  • Long Dry Season (June – October): This is the peak visitor period due to the most stable weather and clear skies. July and August are particularly busy, coinciding with Northern Hemisphere holidays.
  • Short Dry Season (January – March): A popular window with high footfall but slightly quieter than the June–October peak. January and February are often cited as the best months for clear views and warm daytime temperatures.
  • Shoulder Seasons (March, June, October, November): These transition months offer a balance of moderate crowds and manageable weather. November brings the “short rains,” but trails are significantly emptier.
  • Rainy Seasons (April – May): The lowest visitor numbers occur during the “long rains”. Trails can be muddy and treacherous, making this suitable only for experienced trekkers seeking absolute solitude.

Geological and Ancient History

Kilimanjaro was formed by volcanic activity along the East African Rift. 

  • 2.5 Million Years Ago: Volcanic activity begins at the Shira centre.
  • 1 Million Years Ago: Eruptions begin at the Mawenzi and Kibo cones.
  • 360,000 Years Ago: The last major eruption occurred.
  • 150,000–200,000 Years Ago: Final volcanic activity at Kibo created the current summit crater.
  • 1000 BC: Evidence of human cultures on the slopes found via stone tools.
  • 150 AD: Ptolemy of Alexandria makes early references to “lands” near the mountain. 

Exploration and Climbing Milestones

The late 19th century marked the beginning of recorded ascents and scientific study. 

  • 1889: Hans Meyer and Ludwig Purtscheller become the first recorded people to reach the summit (Uhuru Peak) on 6 October.
  • 1909: Gertrude Benham of London reaches the summit alone.
  • 1926: Pastor Richard Reusch discovers a dead leopard on the crater rim, a finding later immortalised in literature.
  • 1957: The volcano is officially declared dormant.
  • 1961: Tanganyika gains independence; a torch is placed on the summit, and the peak is renamed Uhuru (“Freedom”).
  • 2020s: Tourism reaches over 35,000–50,000 climbers per year, with various routes established for different skill levels.

Standard Daily Expedition Routine

A typical day on the mountain follows a strict rhythm to manage fatigue and altitude: 

  • 06:00 – 07:00: Wake up and breakfast at camp.
  • 08:00: Begin the day’s trek (typically 4–7 hours of walking).
  • 13:00: Hot lunch followed by further trekking or rest.
  • 17:00: Reach next camp; “hike high, sleep low” acclimatisation walks.
  • 23:00 – 00:00 (Summit Night): Final ascent begins in the dark to reach the peak by sunrise.

WordPress Content Management System (CMS) Timeline Overview

WordPress has evolved from a basic blogging tool in 2003 into a dominant Content Management System (CMS) that powers over 43% of the internet including this https://mark-whitfield.com website. Its history is defined by major version releases, often named after jazz musicians, and shifts toward “Full Site Editing”. 

This WordPress website started around 2021

The Early Years (2001–2005)

  • 2001: French developer Michel Valdrighi launches b2/cafelog, the PHP/MySQL-based blogging software that served as the foundation for WordPress.
  • 2003 (May 27): Matt Mullenweg and Mike Little release WordPress Version 0.7, a fork of b2/cafelog.
  • 2004: Version 1.0 (“Miles Davis”) introduces SEO-friendly permalinks and comment moderation. Version 1.2 (“Mingus”) debuts the plugin architecture, allowing for external extensibility.
  • 2005: Version 1.5 (“Strayhorn”) introduces the Themes system and static Pages, moving WordPress beyond just chronological blog posts. Automattic is founded by Matt Mullenweg in August. 

Expansion and Ecosystem Growth (2006–2010)

  • 2006: The first WordCamp is held in San Francisco. Automattic registers the WordPress trademark.
  • 2007: Version 2.1 (“Ella”) adds autosave and spell-check. Version 2.2 (“Getz”) introduces Widgets.
  • 2008: Version 2.7 (“Coltrane”) revamps the dashboard, moving the menu to the sidebar where it remains today.
  • 2010: Version 3.0 (“Thelonious”) is a major milestone, introducing Custom Post Types and Multisite capabilities. The WordPress trademark is transferred to the non-profit WordPress Foundation

The “Modern” Dashboard & Visual Improvements (2011–2017)

  • 2011: WooCommerce is released (later acquired by Automattic in 2015), revolutionising WordPress e-commerce.
  • 2013: Version 3.7 (“Basie”) introduces automatic background updates for security patches. Version 3.8 (“Parker”) gives the admin dashboard the modern, flat design used today.
  • 2014: Version 4.0 (“Benny”) focuses on media management with a new grid view.
  • 2016: The REST API is integrated into core (v4.4), allowing WordPress to interact with other web applications. 

The Gutenberg & Site Editing Era (2018–Present)

  • 2018 (Dec 6): Version 5.0 (“Bebo”) launches the Gutenberg block-based editor, fundamentally changing content creation from text-heavy to visual blocks.
  • 2022: Version 6.0 introduces Full Site Editing (FSE), enabling users to edit headers, footers, and templates visually without code.
  • 2024: WordPress continues to refine the site editing experience with Version 6.7 (“Rollins”). In late 2024, a public legal conflict began between Automattic and WP Engine over trademark usage and contributions.

Microsoft Project Timeline, Development History Overview

Microsoft Project has evolved from a DOS-based tool in the 1980s into a cloud-integrated platform. Its “Timeline” feature specifically has transitioned from a simple static view to a multi-layered, interactive reporting tool. 

Template included in package – see website banner

Timeline Feature Development History

  • Early Era (1984–2007): For decades, the “timeline” was synonymous with the Gantt Chart. Users had to rely on complex print-outs or third-party tools to create high-level summaries for executives.
  • The dedicated Timeline View (2010): Microsoft introduced a native Timeline view in Project 2010, allowing users to cherry-pick specific tasks and milestones to display on a single horizontal bar.
  • Multi-Timeline Support (2016): Project 2016 expanded this by allowing multiple timeline bars in a single view. This enabled managers to represent different project phases or workstreams with independent start and end dates.
  • Cloud & Web Integration (2019–Present): With the launch of Project for the web, timelines became more interactive, supporting drag-and-drop adjustments and real-time co-authoring.
  • Task History Tracking (2023): Microsoft added a Task History pane to the web version, allowing users to see a chronological log of changes to specific timeline items. 

Key Components of a Modern MS Project Timeline

Templates included in download bundle – see website banner
  • Gantt-Style Visualization: Displays tasks as horizontal bars against a calendar timescale.
  • Milestones & Callouts: Important dates appear as diamonds or labels that can be dragged above or below the main bar to avoid clutter.
  • Dependencies: Visual links between tasks that illustrate the sequence of work and the Critical Path.
  • Copy for Presentation: A dedicated formatting tool that allows users to export the timeline directly to Microsoft PowerPoint or email at various sizes (Small, Medium, Full Size). 

Future Outlook

Template included in download bundle – see website banner

Microsoft has announced that Project Online will be officially retired on 30 September 2026, with development focus shifting entirely to the new Microsoft Planner and Project for the web ecosystem.
