The earliest payroll changes would go into effect is mid-2019.
------------------In 2015, Colorado legislators passed HB 15-1392, which shifts the state from its current once-a-month pay cycle to a biweekly (every other week) system. The bill will go into effect on July 1, 2018.
DPA has put together an informational page about the switch to biweekly lag pay: https://www.colorado.gov/pacific/dpa/biweekly-lag-pay-implementation
