Earliest Finish Time Solution

STEP 0: Pre-Calculation Summary
Formula Used
Earliest Finish Time = Latest Finish Time-Total Float
EFT = LFT-TF0
This formula uses 3 Variables
Variables Used
Earliest Finish Time - (Measured in Second) - Earliest Finish Time is the time of an activity that occurs if the activity starts at the earliest start time and takes an estimated time t to complete the activity.
Latest Finish Time - (Measured in Second) - Latest Finish Time is the latest time at which the activity can be completed without delaying the project.
Total Float - (Measured in Second) - Total float is the period by which an activity can shift its timing without affecting the relevant schedule completion date.
STEP 1: Convert Input(s) to Base Unit
Latest Finish Time: 50 Day --> 4320000 Second (Check conversion here)
Total Float: 24 Day --> 2073600 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
EFT = LFT-TF0 --> 4320000-2073600
Evaluating ... ...
EFT = 2246400
STEP 3: Convert Result to Output's Unit
2246400 Second -->26 Day (Check conversion here)
FINAL ANSWER
26 Day <-- Earliest Finish Time
(Calculation completed in 00.004 seconds)

Earliest Finish Time Formula

Earliest Finish Time = Latest Finish Time-Total Float
EFT = LFT-TF0

What is Float?

Float, sometimes called slack, is the amount of time an activity, network path, or project can be delayed from the early start without changing the completion date of the project.

What is Slack?

The Slack time for an activity is the time between its earliest and latest start time or between its earliest and latest finish time. Slack is the amount of time that an activity can be delayed past its earliest start or earliest finish without delaying the project.
