The Timezone Struggle is Real
- 🔍Open new tab, search "8 AM EST to IST (India Standard Time)" — every single time.
- 😵Forget AM or PM in the other timezone and second-guess yourself.
- ⏰Miss meetings due to daylight saving time confusion.
- 📋Copy-paste times between apps constantly — there's a better way.
Three Steps. Zero Friction.
Highlight text, get local time, and keep moving.
