Illustrative example. The dates and amounts below are provided for practice.
A work anniversary falls on January 3, and a review happens on December 30. Subtracting the year numbers too early can make the upcoming anniversary look complete.
Enter January 3, 2020 as Start Date, choose Work Anniversary, and set Calculate As Of to December 30, 2026. The result shows six completed years. The next anniversary is January 3, 2027, four elapsed days away.
Keep the two years in view
The countdown crosses December 31 and January 1. The completed-year count increases to seven on January 3, not when the calendar changes to 2027.
If December 30 is called inclusive Day 1 of a short countdown sequence, January 3 is Day 5. The tool displays the four elapsed intervals instead.
Prepare before the holiday
A message can be drafted in December and sent on the anniversary. If printing a card or arranging lunch, save a separate one-time preparation date. Calendar-day lead time includes weekends and holidays.
Changing Calculate As Of to January 3, 2027 is a useful final check. The next anniversary includes that same date, and Days Until Next Anniversary becomes zero.
