Enter the target date, start date, and workload into the calculator to determine the deadline.

Deadlines Formula

The following formula is used to calculate the deadlines.

D = (T - S) / W


  • D is the deadline in days T is the target date S is the start date W is the workload in hours per day

To calculate the deadline, subtract the start date from the target date to get the total number of days available. Then divide this by the workload in hours per day. This will give you the deadline in days.

What is a Deadlines?

A deadline is a set date or time by which a task or project must be completed. It serves as a time management tool, ensuring that tasks are completed in a timely manner and helping to prioritize tasks based on their urgency. Deadlines can be set for personal tasks or within a professional setting, such as a workplace or school, and missing a deadline can have various consequences depending on the context.

How to Calculate Deadlines?

The following steps outline how to calculate the Deadline for a task.

  1. First, determine the Target date (T) in days.
  2. Next, determine the Start date (S) in days.
  3. Next, determine the Workload per day (W) in hours.
  4. Next, gather the formula from above = D = (T – S) / W.
  5. Finally, calculate the Deadline (D) in days.
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Target date (T) = 20 days

Start date (S) = 5 days

Workload per day (W) = 8 hours
