This report presents a comprehensive statistical analysis of 28,515 Hindu calendar events recorded over the period 1900–2100. The study explores how…

A bar chart has been generated showing how festivals are distributed across the days of the week. The visualization uses a color gradient to highlight which days have more or fewer festivals, making it easy to spot the busiest day at a glance.

Chaitra is the Hindu month with the most festivals, containing 4,077 festivals. It is followed by Kartika (3,561), Bhadrapada (3,270), Ashwina (3,230), and Shravana (2,179). A bar chart has been generated showing the festival counts across all Hindu months, making it easy to compare their relative activity.

The analysis reveals which tithi values appear most frequently in calendar titles. Shukla Purnima is by far the most common tithi, appearing 5,099 times. A horizontal bar chart has been generated showing the top 15 most frequent tithi values, making it easy to compare their relative frequencies at a glance.

October has the highest concentration of titled events, accounting for 13.6% of all 28,515 titled events in the dataset. September and April follow closely behind. A bar chart has been generated showing the full distribution across all 12 months.

The analysis reveals which titles appear most frequently versus rarely across years (1900–2100). Two bar charts and supporting tables were generated to visualize the findings. Most titles appear consistently across all 201 years, but a few stand out as either more frequent or uniquely rare.

The most frequent tithi and weekday combination is Shukla Purnima (Full Moon) on Thursday, appearing 782 times across the 1900–2100 period. A bar chart and data tables have been generated showing the top 15 combinations by frequency.

The analysis successfully identified the most frequently occurring Hindu months across all recorded events from 1900 to 2100. A horizontal bar chart has been generated showing the top 15 Hindu months ranked from highest to lowest frequency, making it easy to see which lunar months host the most religious observances. Supporting data tables are also available with exact counts and percentage shares for each month.

The analysis examined Hindu calendar event density across the full 1900–2100 span. A line chart with a 10-year rolling average was generated, showing how event counts fluctuate year to year while remaining remarkably consistent overall. The average is about 142 events per year, with very little variation between the earliest and latest periods of the dataset.

The analysis successfully produced two interactive charts and multiple data tables comparing festival title frequencies across all 7 days of the week. The grouped bar chart shows the top 5 most frequent festival titles for each weekday side by side, making it easy to spot which festivals dominate on specific days. A second chart reveals how broadly each festival title spreads across weekdays — some titles appear in the top 5 on many days (uniform presence), while others are strongly tied to just one or two specific days.

A data table was generated summarizing the distribution of Hindu calendar events across decades from 1900 to 2100. The analysis grouped events by decade, counted totals, and flagged any decades that deviate significantly from the average recording density.
