The reform also applied to [[Caroline Islands]], [[Guam]], [[Marianas Islands]], [[Marshall Islands]], and [[Palau]] as part of the [[Captaincy General of the Philippines]].<ref>{{Cite web|url=https://www.facebook.com/pvinta/photos/a.1924058474508083/2862176590696262/|title=CURRENT PH CALENDAR BEGINS|publisher=Project Vinta|date=January 1, 2021|language=EN|website=Facebook|access-date=April 19, 2023}}</ref>
