Possible disadvantages

  • Limited Public Awareness
    ProDevtivity is not widely known in the developer community compared to more established productivity tools, which means fewer community resources, tutorials, and peer support are available.
  • Niche Ecosystem Lock-in
    The tool appears to be primarily focused on the Microsoft/.NET ecosystem, which limits its usefulness for developers working with other technology stacks such as Java, Python, or JavaScript-heavy environments.
  • Learning Curve
    Like many productivity and code generation tools, there can be an initial learning curve to understand how to configure and effectively use all features, which may temporarily slow down developers before they see productivity gains.
  • Limited Third-Party Reviews
    There are relatively few independent reviews and user testimonials available publicly, making it difficult for potential users to assess the tool's real-world effectiveness and reliability before committing.
  • Potential Over-Reliance on Generated Code
    Heavy use of code generation tools can lead developers to become overly reliant on generated output, potentially reducing their understanding of underlying code patterns and making debugging or customization more challenging.

Questions & Answers

As answered by people managing Working Days Calc and ProDevtivity.

What makes your product unique?

Working Days Calc's answer

Most business day calculators are built for one country. WorkingDaysCalc.com covers 100+ countries using a live public holidays database, so the result changes based on where you are. Five separate calculators handle the most common tasks: counting days between two dates, adding or subtracting business days, calculating a notice period end date, and finding a deadline. No signup, no account, no download.

Why should a person choose your product over its competitors?

Working Days Calc's answer

The main alternatives are either US-only, buried inside a larger tool, or so cluttered with ads that finding the result takes longer than counting by hand. WorkingDaysCalc pulls live public holiday data for each country rather than using a hardcoded list that goes stale. The five calculators cover the specific tasks people search for rather than forcing one generic tool to do everything.

How would you describe the primary audience of your product?

Working Days Calc's answer

HR teams checking notice periods and last working days. Payroll teams confirming payment dates. Legal teams counting court or contract deadlines. Project managers working out delivery windows and milestones. The site gets traffic from the US, UK, Australia, South Africa, and Canada, which reflects where business day calculations come up most in employment law and contract work.

What's the story behind your product?

Working Days Calc's answer

I got a notice period calculation wrong. Counted four weeks forward, told someone their last working day, then spotted a public holiday sitting in that range. Wrong date. In employment and legal contexts, that error has real cost. I looked for a tool that handled multiple countries with accurate holiday data and found nothing that did it cleanly. So I built five calculators that do exactly that and launched the site in June 2026.

Which are the primary technologies used for building your product?

Working Days Calc's answer

WordPress with the Astra theme handles the site structure. Rank Math manages SEO. WPCode handles custom schema and JavaScript snippets. LiteSpeed Cache runs on Hostinger shared hosting. The calculator logic is vanilla JavaScript. Country dropdowns use TomSelect. Public holiday data comes from the Nager.Date API, which covers 100+ countries and requires no API key.

Who are some of the biggest customers of your product?

Working Days Calc's answer

WorkingDaysCalc is a free public tool with no accounts or paid plans, so there are no named customers to list. It gets used by HR professionals, payroll teams, legal staff, and project managers across the US, UK, Australia, South Africa, and Canada.
