As answered by people managing Trello and WeekLeft.
WeekLeft's answer:
Next.js, React, Vercel
WeekLeft's answer:
WeekLeft keeps every calculator focused on one question and answers it instantly. There are no no pop-ups and no cluttered pages. Business day calculations skip weekends automatically, and every result is easy to read on both mobile and desktop.
WeekLeft's answer:
Big sites like timeanddate.com cover hundreds of topics, so finding the right tool can take time. WeekLeft is built only for date and time math, so each calculator is quick to find, simple to use and loads fast. It is completely free, and each tool comes with a short guide explaining how the calculation works.
WeekLeft's answer:
People who need quick date answers in daily life and work: HR and payroll teams counting business days, project managers planning deadlines, students tracking exam dates, and anyone counting down to an event or checking how many weeks are left in the year.
WeekLeft's answer:
WeekLeft started as a small WordPress site with a few calculators. As it grew, it became slow and hard to maintain, so I rebuilt it from scratch in Next.js. During the rebuild I audited the whole site and fixed around 200 issues, including calculation errors, SEO problems and page speed. The goal now is simple: build the most reliable and easy to use date calculators on the web.

Our world has more Todo lists than anyone could count, however, my ready-to-go solution is still Trello when it's time to track my tasks. It's easy to use, colorful, simple and user-friendly without being bloated. - Source: dev.to / 5 months ago

The weird thing is that we accepted online-first or even online-only note taking apps. I used to be a huge fan of Trello and later Notion, but their online-first nature ended up getting in the way. Nowadays I just use a very simple... - Source: dev.to / about 1 year ago
