Number of Days Calculation Form Template
Collect date inputs and calculate the number of days between them automatically.
When you need to calculate durations — days between events, deadline countdowns, project lengths — doing it manually across many inputs takes time and introduces errors. Asking people to do the math themselves and enter the result is unreliable.
A date calculation form collects start and end dates from users and can display or pass through the calculated difference for downstream use. Typeform's date fields capture input clearly, and integrations with tools like Google Sheets, Zapier, or Airtable let you perform the calculation automatically on the backend as soon as a response comes in.
Use it for project tracking, event planning, leave calculations, or any other context where you need to know how many days exist between 2 points in time.
A number of days calculation form collects 2 dates from a user — typically a start date and end date — and is used to calculate the duration in days between them. It's useful for project management, HR, event planning, and any context that involves date-based calculations.
Asking users to calculate a duration themselves and enter the result introduces errors. A form that collects the raw dates and passes them to a calculation tool ensures accuracy and saves the user from doing mental math.
The core fields are simple, but context matters:
- Purpose of the date range (project, leave request, event, etc.)
- Start date
- End date
- Optionally: whether to include or exclude weekends and holidays
- Submitter's name and contact information
- Any notes about the date range
Typeform doesn't natively calculate the difference between 2 date fields and display it in the form. To calculate the number of days, connect your form to Google Sheets (which supports date arithmetic) or use a Zapier integration with a calculation step. The result can then be stored or sent back to the user via email.
Common use cases include PTO duration verification (checking that a requested leave period matches the number of days stated), project scoping (logging start and end dates to track duration), event countdown tracking, and contract duration documentation.
