Add or subtract days, weeks, months or years to any date - instantly find what date falls before or after.
Operation
Stop counting calendar squares by hand - get the exact date in one step.
Works in both directions - jump forward to a future date or backward to a past one with equal ease.
Add days, weeks, months or years. Each unit respects real calendar lengths - adding a month to 31 Jan correctly lands on the last day of Feb.
See the result's day of week, ISO week number, and how many days it falls from today - no extra calculations needed.
Use the date picker to set your starting point. Defaults to today so you can get an answer in seconds.
Choose Add or Subtract, type the amount, and pick the unit - days, weeks, months or years.
The exact result date appears instantly, along with the day of week and how far it falls from today.
Adding or subtracting days, weeks, months, or years from a date is a common need in both professional and daily life. Legal contracts in India often specify delivery or response deadlines as a fixed number of days from a trigger event - for instance, the Consumer Protection Act, 2019 requires complaints to be filed within 2 years of the cause of action, and RERA mandates 30-day resolution timelines. Precisely counting these periods requires accounting for varying month lengths and leap years, which manual calculation often gets wrong.
Date arithmetic is essential across many domains. GST return deadlines are typically the 20th of the following month - filing late incurs Rs 50 per day interest. Income tax advance tax instalments fall on 15th June, 15th September, 15th December, and 15th March. Doctors calculate due dates by adding 280 days (40 weeks) to the last menstrual period. Court practitioners calculate limitation periods. HR departments compute notice periods and gratuity eligibility - the Payment of Gratuity Act requires 5 continuous years of service, calculated precisely from joining date.
Select your starting date, choose whether to add or subtract, and enter the number of days, weeks, months, or years. The result updates instantly with the exact date. You can also mix units - for example, adding 1 year, 3 months, and 15 days simultaneously - making this tool flexible for complex date calculations used in project planning, legal timelines, or financial scheduling.
