Table Structures and Data Types:

Sheet 1: Annual Overview (Gantt Chart)

This sheet visualizes your habits on a timeline. The table spans from January 1 to December 31, with each column representing one week.

• Column A: Habit Name – Text (e.g., "Morning Meditation", "Daily Exercise", "Read 20 Pages")
• Column B: Start Date – Date (e.g., 1/1/2025)
• Column C: End Date – Date (e.g., 12/31/2025 for lifelong habits)
• Columns D to ZI (Weeks): Each cell represents a week and contains either "✓" for completed, "○" for in progress, or blank for not started.

Sheet 2: Habit Tracker

This sheet logs daily habit completion with detailed data entries.

• Date (Column A): Date type (auto-filled from Jan 1 to Dec 31)
• Habit Name (Column B): Text – matches the list in the Annual Overview
• Completed? (Column C): Boolean – TRUE/FALSE or "Yes"/"No"
• Streak Count (Column D): Number – counts consecutive days completed
• Notes (Column E): Text – optional journaling for insights or obstacles

Sheet 3: Quarterly Review

• Quarter (Column A): Text – "Q1", "Q2", etc.

• Challenges Faced (Column D): Text – free-form notes
• Success Factors (Column E): Text – what worked well
• Adjustments for Next Quarter (Column F): Text – revised goals or strategies

Required Formulas:

• =IF(AND(B2<>"", C2<>""), EDATE(B2, 1), "Not Started") – auto-calculates end date for recurring habits.
• =COUNTIFS(HabitTracker!B:B, [@Habit], HabitTracker!C:C, TRUE) – counts total completions per habit in the tracker.
• =IF(D2="", 0, D2+1) – calculates streaks (requires sorting by date).
• =COUNTIFS(HabitTracker!B:B, [@Habit], HabitTracker!C:C, TRUE) / COUNTIFS(HabitTracker!B:B, [@Habit]) * 100 – computes habit completion percentage.
• =IF(AND(Start_Date <= TODAY(), End_Date >= TODAY()), "Active", IF(TODAY() < Start_Date, "Pending", "Completed")) – shows current status of each habit.

Conditional Formatting:

• Habit Progress Bars (Annual Overview): Uses data bars to visualize completion rate per habit across the year.
• Streak Indicator (Habit Tracker): Highlights cells in green if streak ≥ 7 days, yellow for 3–6 days, red for less than 3.
• Status Color-Coding: Habit names are color-coded based on current status: Green (Active), Gray (Pending), Red (Overdue).
