Features and specs

What each product offers, as listed by its team.

Day-Number 3 features
CloudLinux 5 features
  • Day Number Tracking
    Instantly see which day of the year it is (1-365/366). Perfect for academic calendars, business reporting, and year progress tracking.
  • ISO 8601 Week Numbers
    View current week numbers with Monday as the first day of the week, widely used across Europe and international business standards.
  • Date Calculator
    Convert dates to day numbers or find dates from day numbers. Perfect for tracking project milestones or planning seasonal work.
  • Enhanced Server Stability
    CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
  • Improved Security with HardenedPHP and KernelCare
    CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
  • Resource Limit Management
    Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
  • CageFS File System Virtualization
    CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
  • Wide Compatibility with Hosting Panels
    CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

  • Additional Licensing Cost
    CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
  • Limited to CentOS/RHEL-Based Systems
    CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
  • Learning Curve for Configuration
    While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
  • Potential Performance Overhead
    The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
  • Dependency on CloudLinux Ecosystem
    Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.

  • Businesses requiring extended OS support lifecycles beyond standard RHEL/CentOS EOL dates
  • Enterprises using cPanel or Plesk that want tighter security and resource control
  • Hosting companies looking to reduce support tickets caused by noisy-neighbor resource contention

Questions & Answers

As answered by people managing Day-Number and CloudLinux.

What makes your product unique?

Day-Number's answer

Day-Number automatically detects your timezone and location, then displays ISO 8601-compliant day numbers, week numbers, and country-specific holidays - all in one place. Unlike basic calendar tools, we combine real-time timezone intelligence with international holiday support and powerful date calculators in a clean, modern interface.

Why should a person choose your product over its competitors?

Day-Number's answer

We automatically detect your location and adjust everything for you - perfect for travelers and remote workers. We provide accurate ISO week numbers (which many tools get wrong), support multiple date format standards, show upcoming holidays for your country, and include powerful date calculators. Everything is free, privacy-focused, and works beautifully across all devices.

How would you describe the primary audience of your product?

Day-Number's answer

Remote workers and digital nomads managing multiple timezones, developers and project managers who work with ISO date standards, international teams coordinating across different countries, and anyone who needs quick access to standardized date information without complex calendar apps.

What's the story behind your product?

Day-Number's answer

As developers working with international teams, we constantly needed to answer "What's today's ISO week number?" or "How many days until the deadline?" Existing tools either lacked timezone intelligence or showed incorrect ISO calculations. We built Day-Number as the tool we wished existed - one that instantly shows where you are in time, no matter where you are in the world.

Which are the primary technologies used for building your product?

Day-Number's answer

Next.js 15 with React 19 and TypeScript for performance and maintainability, Tailwind CSS for responsive design, date-fns-tz for precise timezone calculations, and next-intl for internationalization. We use ipapi.co for geolocation and Nager.Date for holiday data, deployed on Vercel's edge network for global availability.

Who are some of the biggest customers of your product?

Day-Number's answer

As a free public tool, we serve thousands of individual users rather than traditional customers - including developers relying on accurate ISO standards, international businesses managing multi-timezone operations, and remote-first companies. We're adopted particularly in tech hubs across North America, Europe, and Asia, especially among digital nomad communities.
