Track time across timezones, convert unix timestamps, and calculate dates. All in your browser.

Date Math lets you add or subtract days, weeks, months, or years from any start date. Pick a start date, choose an operation (add/subtract), enter an amount, and select a unit. The result updates instantly — perfect for calculating deadlines, project timelines, or expiration dates.
