Date & Time Tools
Free date and time tools: date calculator, countdown timer, work days calculator, Unix timestamp converter and days until date.
Date math looks trivial until calendars fight back: leap years, months of different lengths, business-day conventions and time zones that shift with the seasons. These tools handle the edge cases so your deadline, countdown or timestamp is right the first time.
Everything is plain calendar dates — no time-zone surprises — and business-day counting follows the standard weekend-exclusion convention used by contracts worldwide.
