# Time Frames & Time Conversions

When we talk about "mid morning", or "late afternoon", do you really know what time frame specifically we are referring to? Perhaps even more confusing to some people is the "Z" time (also called UTC or GMT time) mentioned in most meteorological text and graphics. Without the proper knowledge, there can be a lot of confusion. Below you will find simple conversions of both aspects.

Overnight -- Midnight to 6:00am.

• Early Overnight...... 12:00AM - 2:00AM
• Mid Overnight...... 2:00AM - 4:00AM
• Late Overnight...... 4:00AM - 6:00AM
• Morning -- 6:00AM to 12:00PM.

• Early Morning...... 6:00AM - 8:00AM
• Mid Morning...... 8:00AM - 10:00AM
• Late Morning...... 10:00AM - 12:00PM/noon-time
• Afternoon -- 12:00PM to 6:00PM.

• Early Afternoon...... 12:00PM/noon-time - 2:00PM
• Mid Afternoon...... 2:00PM - 4:00PM
• Late Afternoon...... 4:00PM - 6:00PM
• Evening -- 6:00PM to 12:00AM/Midnight.

• Early Evening...... 6:00PM - 8:00PM
• Mid Evening...... 8:00PM - 10:00PM
• Late Evening...... 10:00PM - 12:00AM/Midnight

Z time, also called UTC or GMT time, is a universally coordinated time used in operational meteorology world-wide. If you're just learning it, it will be a bit confusing... but you'll get the hang of it after a while. To find the Z time during Standard time, add 5 hours to the 24 hour time. During Daylight time, add 4 hours to the 24 hour time. For example, 13:00 (1pm) would be 18Z in Standard time, and 17Z in Daylight time. Below is a conversion chart with 12 hour time, 24 hour time, and Z time listed, for both Standard and Daylight time:
