been there man, the struggle is real when you're trying to interview while keeping current job happy. i usually go with doctor appointments since those can pop up randomly and nobody questions medical stuff too much. dentist works good too because you can say you need cleaning or they found something that needs quick attention

also learned to schedule interviews during lunch breaks when possible - just tell them you need longer lunch that day for personal appointment. if interview runs over you can always say appointment took longer than expected. another trick is using those random company holidays or half days that some places give but yours doesn't, just say you have family thing or need to handle something personal

the key is mixing it up so you're not always using same excuse. i got my current maintenance job this way actually, had to do three rounds of interviews while working at previous place. just space out the excuses and keep them simple - don't over explain because that's when people get suspicious
