Our mission is simple: to help you maximize your time off and reclaim your free time.
Booking time off shouldn't feel like playing a game of Tetris blindfolded. If you've ever found yourself staring at a calendar in January, trying to guess which days will give you the longest breaks around public bank holidays, you know the struggle.
Most people waste their precious annual leave on random scattered days, missing out on secret combinations that could have turned 15 days of PTO into 40 straight days out of the office.
HolidayStacks was built by time hackers who were tired of doing the math manually. We wrote a highly optimized mathematical engine that does the heavy lifting for you. It instantly scans hundreds of thousands of date combinations in milliseconds to output the perfect year of rest.
We also believe in 100% privacy. Unlike other tools that demand access to your work Google Calendar or Outlook, our algorithm runs entirely in your browser window. No accounts. No tracking. Just you hacking the system.
We don't do vibes. We do math. The engine ensures you get the undeniable, absolute maximum return on your hours.
Rest is a necessity, not a luxury. By optimizing your calendar, we hope you spend less time working and more time living.
We've ingested the bank holiday schedules for over 100 countries and regions worldwide so anyone can stack.
