Acknowledgments, References, and Credits

"I value the friend who for me finds time on his calendar, but I cherish the friend who for me does not consult his calendar."
~ Robert Brault, writer

The author would like to thank, first and foremost, Dr. Irvin Bromberg of the University of Toronto for innumerable helpful suggestions and criticisms of early drafts of the XRS Calendar—and for his openness in sharing his knowledge with many other designers of reform calendars. Because Dr. Bromberg has put forth a number of his own proposals for calendar reform, this acknowledgment should not be construed to imply that he endorses use of the Extended-Range Secular Calendar for any purpose whatsoever.
