WHY THIS COLLECTION EXISTS
One question usually leads to another.
These pages group tools by user intent rather than dumping every EgoTools experience into one giant list. That makes it easier to find the next relevant tool and gives search engines a clearer picture of how the site is organised.
DATE CALCULATIONS, NOT SHORTCUTS
Calendar months have different lengths and leap years exist, so EgoTools date tools work from real calendar dates rather than pretending every month has 30 days or every year has 365.
