Calculate any date, forward or backward, instantly

I'm Gohar, founder of 90daysfromtoday.org. It's a free tool that calculates any number of days forward or backward from any starting date, whether that's today, a past date, or a future date. It can also calculate using working days only, skipping weekends. Results show up in multiple formats, plus a full calendar view.

I built it because most date calculators are cluttered with ads or require signups just to get a simple answer. Mine is instant and clean.

Would love your feedback, and I'm curious what date calculators (if any) you currently use.
