Date Tools
8 tools for counting days, ages and dates
8 toolsFind out how many days lie between two dates, how many days are left until a date, or what date it will be 90 days from today. The age calculator gives your exact age in years, months and days; the week number tool follows the ISO 8601 standard.
All tools handle leap years, month ends and weekends correctly, and business-day counts skip Saturdays and Sundays. For holidays and special dates, see our Days Until pages.
