Convert Military Time to Regular Time

People type military time many ways: 1430, 14:30, 14:30:45, 1430 hrs, 14h30. Rather than fighting that, the parser strips delimiters, identifies digit count (1-6), and assigns hours/minutes/seconds accordingly. 8 means 0800; 143045 means 14:30:45. The error message is specific when something genuinely won’t parse.

Military uses 25 single-letter timezone codes (A-M for east of UTC, N-Y for west, Z for UTC itself, J for “local”). So 1430Z means 14:30 Zulu = 14:30 UTC. 1430R means 14:30 Romeo = 14:30 US Eastern (UTC-5). The result panel shows the zone name, offset, and a sample country/region – useful when reading NATO logs or aviation timestamps.

By formal convention, midnight at the end of a day is 2400; the next instant (start of the next day) is 0000. Some systems use 2400 in scheduling (“shift ends at 2400”). The tool accepts 2400, returns 12:00 AM, and adds a note explaining it’s the end-of-day midnight equivalent. Most calculators reject this silently or with a vague “hours out of range”.

0000 is midnight (start of day) = 12:00 AM. 1200 is noon = 12:00 PM. The AM/PM convention is genuinely confusing here – “12 AM” and “12 PM” don’t fit the “AM = ante meridiem (before noon)” rule cleanly. Convention: midnight is 12 AM, noon is 12 PM. Military notation is unambiguous: 0000 vs 1200.

Yes – switch direction (or click Swap ⇄). Regular input accepts 2:30 PM, 02:30 PM, 2:30 p.m., 14:30 (also works without AM/PM since 14 is unambiguous), even literal noon / midnight. Output is 4-digit military (1430) plus all the cross-reference fields.

Tick the Batch box. Paste any number of values, one per line – they can be mixed formats (0800, 14:30:45, 2400, 2359R). Output is a tab-separated table with columns: input, regular, military4, 24h, iso, zone. Invalid rows show “ERR” in the second column. Paste straight into Excel – tabs split into cells.

By design – this is a notation converter, not a wall-clock-shift calculator. 1430Z means “14:30 expressed in Zulu time”, so the regular output is 2:30 PM (Zulu). If you also want to know what 1430Z is in Pacific Time, you’d subtract 8 hours separately: 06:30 AM PST. We show the zone label only, not the shifted local time, to keep the conversion math transparent.

Yes. 143045 or 14:30:45 both parse as 14:30:45. The regular-time output appends seconds when present: 2:30:45 PM. Most simple military-time converters silently truncate the seconds; this one preserves them through to the ISO 8601 output.

No. All parsing and formatting runs in your browser using vanilla JavaScript. Open DevTools → Network and confirm zero requests fire after the page loads – even when you Convert or switch modes. Safe for confidential schedule data or operational logs.

Yes. Total bundle is under 20 KB. Once loaded, disconnect and keep converting. Useful for prepping shift schedules or military reports in disconnected environments (vessels, aircraft, secure facilities).
