Year End Timestamp

Find the Unix timestamp for the next year boundary and copy common date-range values for annual reports and scripts.

End-of-year boundary

For most database filters, the clean boundary is the start of next year at 00:00:00 UTC. Use it as an exclusive upper bound: created_at >= yearStart and created_at < nextYearStart.

Why exclusive upper bounds are safer

Exclusive upper bounds avoid off-by-one-second and millisecond precision bugs. They also work cleanly across databases that store fractional seconds.
