Date and time
Days between dates, working days, age, countdowns and time cards.
8 calculators
- Days Between Dates CalculatorPick two dates and get the number of days between them, along with how many of those are working days.
- Date Difference CalculatorThe gap between two dates in years, months and days, counted the way a calendar counts rather than by dividing into a flat 30-day month.
- Date CalculatorAdd or subtract any span from a date. Months and years move the calendar rather than adding a fixed number of days, which is what a deadline or a lease actually means.
- Business Days CalculatorCount the working days between two dates, or find the date a number of working days from now. Weekends come off automatically and you can subtract holidays.
- Countdown CalculatorHow long until the date that matters. Days, weeks and working days left, plus how far through the wait you already are.
- Age CalculatorYour exact age in years, months and days, and how long until the next birthday. Change the second date to find your age at any other moment.
- Hours CalculatorHow many hours between two times, with the break taken off. Type times any way you like: 9am, 9:00, 17:30 and 5:30 pm all work.
- Time Zone ConverterPick a date, a time and two zones. Daylight saving is handled for you, so a meeting set in March still lands correctly in November.
Counting days and hours
The days between dates and date difference calculators count calendar days, with the option to include the end date. The business days calculator leaves out weekends and, where you choose, public holidays, which is how most deadlines and delivery times are counted.
The date calculator adds or takes away days, weeks or months from a date. Adding a month to January 31 runs into a shorter month, and the calculator gives the last day of the shorter month, February 28, rather than rolling into March. The age calculator gives an exact age in years, months and days.
The hours calculator adds up time cards, including breaks and shifts that pass midnight. The time zone converter accounts for daylight saving time on the date you choose.
