Calculate your net years of experience and spot resume date gaps.
See how applicant tracking calculators sum your work history: merges overlapping concurrent roles so side projects are not double-counted, identifies chronological gaps of 3+ months, and flags seasonal or year-only dates that break Workday and Taleo autofill.

- • Seasonal or quarter date detected in "Product Intern | CampusLabs | Summer 2017". Workday, Taleo, and iCIMS parsers require explicit months (for example, "Jun 2017 - Aug 2017" instead of "Summer 2017").

How ATS platforms calculate total years of experience
When a job posting requires “5+ years of experience,” applicant tracking parsers extract the start and end dates under your Work Experience section, convert each role into a calendar interval, and merge overlapping months before adding them up. If a date line uses seasons (Spring 2022), relative text (3 years), or sits inside a multi-column table where the parser associates your graduation date with a job title, the calculated tenure can drop below the requirement.
After checking your date math here, you can build or import your resume in the Guul editor for free. Plain-text (.txt) resume downloads are free; exporting a finished PDF or Word (.docx) file requires a paid pass such as One Resume or Pro Monthly.
Frequently Asked Questions
Do applicant tracking systems double-count overlapping jobs?
Usually no. When you hold a full-time role and a concurrent part-time or consulting role during the same calendar months, enterprise ATS parsers merge overlapping date intervals before summing total experience. A 3-year full-time job and a simultaneous 1-year advisory role during that same period count as 3 net years of experience, not 4.
What date format works best across Workday, Taleo, iCIMS, and Greenhouse?
Use standard abbreviated or full month names with four-digit years (such as "Mar 2021 - Present" or "March 2021 - November 2023") or numeric "03/2021 - 11/2023". Avoid seasonal dates like "Summer 2022" or bare years like "2021 - 2023", which either fail to parse or cause ambiguous month rounding.
What counts as an employment gap on a resume?
Most recruiters and automated timeline checks only notice gaps of 3 or more consecutive months between chronological roles. If you have a planned parental leave, caregiving period, layoff transition, or degree sabbatical, a brief one-line entry with the date range prevents the parser from treating the period as an unexplained gap.
Is my work history uploaded to a server when I use this calculator?
No. Date parsing, interval merging, and gap detection happen locally in your browser.
