Find your upcoming anniversary milestones
Anniversaries have all sorts of milestones worth marking beyond the obvious yearly one, and knowing when each falls helps you plan ahead for them. This calculator finds your upcoming anniversary milestones, expressed in days, weeks, months and years, all counted from a start date that you provide.
Why milestones beyond the yearly one
The yearly anniversary is the obvious one, but there are plenty of others genuinely worth noticing: a thousand days together, ten thousand days since a business opened, or round numbers of weeks and months that make lovely little moments to mark and celebrate. Calculating all the upcoming milestones from a single start date surfaces these for you, so you can plan a surprise around one or simply take a moment to appreciate them as they pass. It effectively turns one solitary yearly date into a whole series of meaningful moments, which is a genuinely lovely way to look at a relationship, a job, or any ongoing thing you care about.
