Date & Time Calculators
Work hours, durations and dates.
Work Hours
Add up the hours in a shift from the start time, end time and break. Get the result in hours and minutes and in decimal hours for payroll. Handles overnight shifts.
CalculateAge
Work out an exact age from a birth date: years, months and days, plus the total months, weeks and days lived. Use any reference date.
CalculateDays Between
Count the number of days between two dates, plus the gap in weeks and in years, months and days. The order of the dates does not matter.
CalculateDate Calculator
Add or subtract days from a date to find the resulting date and the day of the week. Handy for deadlines, due dates and scheduling.
CalculateCountdown
Count down the days, weeks and months until a future date — a holiday, birthday, deadline or event. Also shows the day of the week it lands on.
CalculateBusiness Days
Count the business days (Monday to Friday) between two dates, and see how many weekend days fall in the range. Excludes public holidays.
CalculateTime Duration
Find the duration between two times of day, in hours and minutes and in decimal hours. Accepts 12-hour (AM/PM) or 24-hour times and handles overnight spans.
CalculateWeeks Between
Count how many weeks are between two dates — as a decimal and as whole weeks plus the leftover days. The order of the dates does not matter.
CalculateMonths Between
Count how many months are between two dates — the calendar difference in years, months and days, plus the total full months. The order of the dates does not matter.
