Filing Date Formula

The following formula is used to estimate a future (target) filing date by adding a duration (in calendar days) to a start date.

FD = CD + PD

Variables:

  • FD is the estimated filing date (target date)
  • CD is the current date (start date)
  • PD is the processing duration (days)

To estimate the filing date, add the processing duration to the current date. The result is a planning target: the start date is day 0, and every subsequent calendar day counts, including weekends and holidays. It does not apply jurisdictional filing rules, cut-off times, or weekend/holiday deadline adjustments.

What is a Filing Date?

An official filing date is determined under the applicable authority’s rules; submission, receipt, and postmark rules can differ. It can affect later timelines and rights. This calculator does not determine that official date or a legal deadline; it estimates a planning target by adding calendar days to a start date.

How to Calculate an Estimated Filing Date?

The following steps outline how to estimate a filing date using the formula FD = CD + PD (calendar days).

  1. First, determine the current date (CD) as your start date.
  2. Next, determine the processing duration (PD) in days.
  3. Next, use the formula FD = CD + PD.
  4. Finally, calculate the estimated filing date (FD) by adding PD calendar days to CD.
  5. 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.

current date (CD) = 2022-10-15

processing duration (PD) = 7 days

estimated filing date (FD) = 2022-10-22
