Who is behind My Payday Cal

My Payday Cal is published by Radif Partners, a company that builds free tools on public rules and data. This site is for employees who want to know when they will be paid, for payroll staff who publish next year’s calendar, and for anyone who needs to count business days or plan around a clock change.

What the site does

It builds a full year of paydays for a weekly, biweekly, semi-monthly or monthly schedule, moves the dates that land on a weekend or a bank holiday by the rule you choose, and exports them as a calendar file or a printable list. It counts the paydays of a year and explains the years with 27 biweekly paychecks, converts a salary into gross pay per paycheck, dates the federal pay periods of each leave year, counts business days on the bank or federal calendar, and counts down to the next clock change in your own time zone.

Where the rules come from

From official texts and tables: 5 U.S.C. 6103 for the holidays, OPM’s federal holiday tables and leave year dates, the Federal Reserve Banks’ holiday schedules, 5 U.S.C. 5504 for federal pay, 15 U.S.C. 260a and NIST for clock changes, the Department of Labor’s Hours Worked Advisor and Title 29 of the Code of Federal Regulations for hours and overtime. Every page links to the sources behind it, and the method page explains each computation.

What we are not

We are not a payroll company, a bank, the Office of Personnel Management, the Federal Reserve or the Department of Labor, and we do not see your employer’s payroll. Your employer sets your payday; this site shows what its schedule and rules produce. The site uses no official seal or logo.

How the site is paid for

The site sells nothing, makes no pay stubs, takes no commission, collects no contact details and links to no payroll provider. If advertising is added one day, it will never sit inside a tool and cannot use what you type, which never leaves your browser.

Tell us when something is wrong

Write to contact@mypaydaycal.com with the page and the date that looks wrong. The editorial policy explains how a correction is made and dated. The site has 19 pages of calendars, guides and tools.
