All Timezone Conversions

Cron IST to EST

Convert cron job schedules from IST to EST timezone.

Timezone Offset

-10.5 hours

IST (UTC+5.5) → EST (UTC-5)

Conversion Examples

To run a job at a specific IST time, use the EST expression below:

Target time (IST) Cron in EST Equivalent EST time
Midnight IST0 13.5 * * *1.5 PM (previous day)
9 AM IST0 22.5 * * *10.5 PM (previous day)
Noon IST0 1.5 * * *1.5 AM
5 PM IST0 6.5 * * *6.5 AM

How to Use

If your server runs in EST but you want jobs to execute at IST times:

  1. Take your desired IST hour
  2. Subtract 10.5 hours
  3. If result is negative, add 24 (job runs previous day)
  4. If result is 24 or more, subtract 24 (job runs next day)

For complex schedules, use our Timezone Converter Tool to see exact run times in both timezones.

Important Notes

  • Standard cron has no timezone support - it uses the server's local time
  • Day boundaries: When converting crosses midnight, the day also changes
  • DST: Consider daylight saving time - offsets may change by 1 hour seasonally
  • Kubernetes & cloud platforms: Many support explicit timezone configuration
