Every date is a number.
Every number between two dates is a record of something lived — days counted, hours worked, years passed, milestones earned.
We are relentless measurers of time, not because numbers are cold, but because they are honest. They witness what we sometimes cannot say in words.
Three years, two months, fourteen days.
That is an anniversary. A sobriety milestone. A countdown to something longed for.
Numbers do not interpret. They simply hold the span. What we bring to them is the meaning.
TimeSpanCalc was built to do one thing cleanly: give you the number. No ads, no account, no calendar to navigate. A keypad, three modes, and a result. Bookmark it. Use it from any device, anywhere in the world.
SPAN — How much time between two dates? Enter two dates. Get the duration in days, weeks, or years. Toggle work days to count Mon–Fri only.
LAND — What date is N days from now? Enter a start date and a duration. Get the exact landing date. Useful for deadlines, expiry dates, and countdowns.
TOTAL — What is the combined time? Add multiple durations together. Useful for timesheets, study sessions, and multi-leg journeys.
My name is Chaofan Wu. My life has been a long conversation with evolving forms of language.
The thread through all of it is the same: language as interface. Whether neurons fire, tokens predict, or code executes, language is not just how we describe reality — it is how we interpret it, respond to it, and quietly shape it in return.
In other work: I co-produced a documentary with an Oscar-winning director in Tibet. I led a K-pop campaign that reached 1.5 billion impressions. I developed bilingual outreach that helped over 300 Chinese-speaking Montrealers join a French language program. I have worked across storytelling, technology, brand strategy, and cross-cultural communication — bringing creativity, technical fluency, and cultural depth to every project.
TimeSpanCalc is one small expression of that belief. Numbers are a language too. This tool helps you read them.
I am open to collaborations where communication, innovation, and meaningful impact meet.
TimeSpanCalc stores nothing. No account. No cookies. No analytics beyond what the hosting provider logs at the network level. Your date calculations stay on your device. The date format preference (MDY / DMY / YMD) is saved locally in your browser so you do not have to set it again on your next visit.
