Show HN: A high-level sprint calendar for checking dates at a glance (opens in new tab)

I'm the product manager for a couple of dev teams, and sometimes need to quickly check where certain future dates fall with our 3-weekly sprint cadence. Neither Outlook's calendar nor our org's internally hosted Jira instance makes this easy to determine at a glance - the latter I can't even access from my phone.

I built something so I can always have a high-level view of our sprint dates on hand when I'm in meetings - stakeholders discussing milestones, team members asking about time off, or upcoming change freeze windows. I figure it might be useful for others, and I was surprised to find this .com domain available, so I nabbed it for sharing.

You can see one of my team's sprints and releases here: https://sprintcalendar.com/3-week-sprints/start-2023-03-23/r.... This bookmarked view won't need to change as time goes on, unless of course my team decides to change or reset its cadence.

It has a few limitations, and likely wouldn't be too useful for teams whose sprints or releases are attached to calendar months instead of weeks. However my last team's "First Sunday of the month" release model was not hard to keep track of in my head.

Feedback welcome!
