Key Features

✓Automatic timezone detection

✓Business hours classification

✓Time-based user segmentation

✓Behavioral pattern analysis

✓Custom time zone support

✓Weekend/weekday detection

Script Overview

📖

What It Does

This script analyzes the visitor's local time to create behavioral segments based on when they visit your site. It detects timezone, classifies visits into business hours, weekend/weekday patterns, and pushes detailed temporal data to GTM for personalized messaging and analytics.

🎯

Use Case

Great for businesses with time-sensitive offers or different messaging for business hours. Perfect for B2B companies that want to tailor messaging based on when prospects are most likely to be working vs browsing personally.

✨

Key Benefits

•Time-based visitor segmentation for personalization
•Business hours vs after-hours visitor classification
•Weekend and weekday behavioral analysis
•Timezone-aware visitor insights
•Enhanced behavioral targeting capabilities
•Temporal conversion pattern analysis
