Manual Method To Add Hours 

Step One: Determine The Starting Time 

Identify the exact time you’re starting from, whether it’s the current time or a future time. For example, Imagine it’s currently 2:30 PM, and you need to schedule a meeting for a few hours later.

 The starting time will be 2:30 PM. 


Step Two: Add Hours To The Starting Time 

Simply add the desired number of hours to the hour part of the starting time.

Suppose you need to schedule the meeting for 3 hours from now. So you will have to add 3 hours to your determined starting time, in this case 2:30 PM:

2:30 PM + 3 hours = 5:30 PM


Therefore, the meeting will be scheduled for 5:30 PM.

Accounting For Time Zones While Calculating Hours 

If you’re dealing with time across different time zones, ensure you adjust the hours accordingly. Remember to consider any differences in time zone offsets when calculating the new time.

Suppose you’re in New York (Eastern Time Zone) scheduling a call with a colleague in Los Angeles (Pacific Time Zone). The current time in New York is 3:00 PM Eastern Time (ET), and you want to schedule the call for 2 hours from now.

New York is in the Eastern Time Zone (ET), which is 3 hours ahead of Los Angeles in the Pacific Time Zone (PT). Adding 2 hours to 3:00 PM ET:

3:00 PM ET + 2 hours = 5:00 PM ET

Since New York is ahead of Los Angeles, you need to subtract the time difference:

5:00 PM ET – 3 hours = 2:00 PM PT

Important Considerations While Adding Hours

Consideration Explanation
Time Format Determine if you are using the 12-hour clock (AM/PM) or the 24-hour clock.
Handling AM/PM In the 12-hour clock system, hours after 12:00 PM (noon) are PM, and after 12:00 AM (midnight) are AM.
Crossing Noon/Midnight When adding hours causes the time to cross noon (12:00 PM) or midnight (12:00 AM), switch from AM to PM or vice versa.
Overflow in 24-Hour Clock If the resulting hour is 24 or more, subtract 24 to get the correct hour.
Minutes and Seconds Make sure that you correctly add and carry over minutes and seconds if they are part of the time calculation.
Day Change Adding hours can change the day, especially when crossing midnight.
Date Context Be aware of the date context when hours are added across days.
Time Zones Consider the impact of different time zones if applicable.


Initial Time Hours to Add Calculation New Time (12-Hour) New Time (24-Hour) Effect
10:00 AM 5 10 + 5 = 15 3:00 PM 15:00 AM to PM transition
11:00 PM 4 23 + 4 = 27 3:00 AM next day 03:00 PM to AM, next day
1:30 PM 6 13:30 + 6 = 19:30 7:30 PM 19:30 PM remains PM
