Martin Šikula

Founder of Whenest

CEO of Šikulovi s.r.o.

Hi there!

I'm Martin, and I built Whenest. By day I run Šikulovi s.r.o., a web agency in Brno, Czech Republic. We build websites, e-shops, and web applications — and along the way we've accumulated a handful of side projects like this one.

Why Whenest exists

Most of my work day involves somebody in a different time zone. A developer in Prague. A client in Portland. A designer we worked with last year was based in Melbourne, so every call happened either at 7am or 10pm. After enough "wait, what time is that for you?" emails, I started paying closer attention to how people actually schedule things across borders.

The honest answer: badly.

Calendar apps show you one zone at a time. World clock sites help, but many of them fumble daylight saving, and sharing a meeting time in Slack tends to devolve into a string of UTC offsets that someone still gets wrong. I tried a few tools and they were either bloated, paywalled, or demanded an account I didn't want to create just to find a 30-minute overlap.

So I built the thing I needed. No signup, no tracking, no pressure to upgrade. Pick your cities, drag the slider, share the link.

What I know about this problem

I've been working with distributed teams for about a decade, both as a freelancer and running an agency. Some of that means coordinating developers across Central Europe and South America. Some of it is client calls in North America. The rest is a quick hello with a stakeholder in Singapore that has to fit before their lunch and after my morning coffee. The small tools you use to glue these conversations together add up — if any of them feels clunky, the whole week feels off.

Daylight saving has been a particular thorn. Twice a year the US shifts a week earlier than the EU does, which means half of my recurring calls silently drift by an hour. Whenest handles that correctly, and the DST alerts exist because I was tired of getting it wrong myself.

Czech LLC operating since 2016, based in Brno. Most of our time goes into client work — building production websites and web applications — but we keep a handful of public tools running because they solve real problems and because open tools teach you things client work never will.
