Why I Made This Time Duration Calculator
📅 I built this Time Duration Calculator because my friend Rahul was planning a big project and kept asking me, "How many days are there between these two dates?" He was trying to figure out his project timeline, but the math was getting complicated.
Then my cousin Priya asked me how many months old her baby was. And my uncle Shyam wanted to know how many days he had worked at his job. Everyone had different needs, but they all wanted one thing: a simple way to calculate time between two dates.
So I created this tool that does all the hard work for you. Whether you want to know the exact age of your child, plan a project timeline, or track a milestone, this calculator gives you the answer in years, months, days, hours, minutes, and even seconds. Just pick two dates, and you're done! ⏱️
