What date is 1764581115 seconds since epoch?
The timestamp 1764581115 is another Unix seconds value. It converts to 2025-12-01T09:25:15.000Z in UTC. If you enter 1764581115 into a JavaScript Date constructor without multiplying by 1000, it will show a date near January 1970 because JavaScript expects milliseconds.
- 1764581115 seconds = 2025-12-01 09:25:15 UTC
- 1764581115000 milliseconds = the same instant for JavaScript Date
- new Date(1764581115 * 1000).toISOString() = 2025-12-01T09:25:15.000Z
- new Date(1764581115).toISOString() = 1970-01-21T10:09:41.115Z
How to compute any year-start timestamp
The start of any year in UTC is the Unix timestamp of January 1 at 00:00:00. Because years are not all the same length — leap years add a day — it is safest to let a date library compute the boundary rather than adding a fixed number of seconds to a previous year.
- JavaScript: Date.UTC(2026, 0, 1) / 1000 = 1767225600
- Python: int(datetime(2026, 1, 1, tzinfo=timezone.utc).timestamp())
- Linux: date -u -d '2026-01-01' +%s
- Start of 2025 in UTC: 1735689600
- Start of 2027 in UTC: 1798761600
